Typical procedure for formylation of aryl halides catalyzed byPdO/Co3O4(Table 2) General procedure: The suspension of 5 wtpercent PdO/Co3O4(20 mg, 1.6 molpercent Pd atomand 47 molpercent Co to substrate) in dioxane (1 mL) in a stainlessautoclave attached a glass tube was stirred at 120C under H2atmosphere (2 MPa) for 2 h. After cooling to RT, aryl halide 1(0.5 mmol), K2CO3(0.5 mmol) and dioxane (1 mL) were added andstirred at 140C for 20 h under CO:H2= 3:1 atmosphere (4 MPa).The reaction mixture was analyzed by GC using tridecane (30 L,0.1 mmol) as an internal standard after filtration through celite toremove the catalyst. The products 2 and 3 were identified by com-parison of the retention time of GC with the authentic samples. Thealdehydes 2a–f and 2h–k were also characterized by1H and13CNMR after chromatographic purifications. Other aldehydes werefound to be difficult to isolate due to low yields and volatilities.

A catalytic amount (0.1 equivalents) of 1,4,7,10,13,16-hexaoxacyclooctadecane (18-Crown-6) was added to the reaction mixture. The product was recrystallized from a mixture of pentane and diethyl ether. The 4-[1-hydroxy-1-(3-(naphth-2-ylmethoxy)phenyl)ethyl]thiazole used as a starting material was obtained as follows: A solution of methyl 4-thiazolyl ketone (Chem. Abs, 89, 197387 y) in tetrahydrofuran was added to an equimolar amount of a Grignard reagent prepared by the reaction of 3-(naphth-2-ylmethoxy)bromobenzene and magnesium under tetrahydrofuran. The reaction mixture was stirred at ambient temperature for 15 minutes, poured into a saturated ammonium chloride solution and extracted with ethyl acetate. The organic layer was dried (MgSO4) and evaporated. There was thus obtained the required starting material in 38percent yield as an oil. The 2-(naphth-2-ylmethoxy)bromobenzene used as a starting material was obtained by the reaction of 2-bromomethylnaphthalene and 3-bromophenol using the conditions described in Example 1. There was thus obtained the required bromobenzene in 68percent yield, m.p. 109°-111° C. (recrystallized from a mixture of ethanol and ethyl acetate).

A solution of the phenyliodonium ylide precursor in dry dimethylformamide (1.0 mL) was added to the dried KFKryptofix complex and the reaction vessel was hermetically sealed. The reaction mixture was heated at 1300C for 15 min. The reaction mixture was cooled to room temperature and processed with a silica gel chromatography column (12 X 1 cm). The products of the reaction were eluted off the column with diethyl ether (20 mL) and analyzed by GC/MS (30 m X 0.25 mm J;W Scientific DB-5MS capillary column; Varian Saturn 2000 mass spectrometer) and by analytical HPLC (Phenomenex Luna Cl 8 column, 5μ particle size, 250 X 4.6 mm; eluent : methanol/water = 75/25; flow rate : 1 mL/min; UV detection at 254 nm).[0046] The products observed by GC/MS and analytical HPLC in these reactions are summarized in Figure 4.[0047] In each of these reactions with the fluoride ion, only three major aromatic products were observed - substitution of the nucleophile on the aromatic ring to yield a fluoroaryl derivative, substitution of hydrogen on the aromatic ring to give the arene and formation of an iodoaryl analog. GC/MS analysis conclusively proved the identity of these products. Analytical HPLC data supported the GC/MS data. The GC/MS analysis showed that the nucleophile (i.e. fluoride) did not substitute on the dione moiety to yield l-fluoro-2,2-dimethyl-l,3-dioxane-4,6-dione (13) (Figure 5, Path B) but instead the fluoride substituted regiospecifically on the phenyl ring on the ipso carbon. This observation can be rationalized by the presence of a delocalized negative charge distributed over the dione part of the dioxane ring system which would repel the nucleophile (i.e. fluoride ion) also carrying a negative charge.; On the other hand, the carbon atom on the aromatic ring carrying the positively charged iodine moiety has an electron deficiency and makes itself a more favorable point for the attack by the nucleophile to yield the fluoroaryl derivative (Figure 5, Path A). Substitution of hydrogen on the aromatic ring to give the hydrocarbon derivatives (i.e. benzene, toluene, mesitylene, anisole etc) strongly indicate involvement of a competing radical pathway for this nucleophilic substitution reaction and abstraction of hydrogen from the solvent. Such a radical pathway has previously been observed in the nucleophilic reaction of fluoride with the closely related iodonium salts (M. Van Der Puy, "Conversion of Diaryiodonium Salts to Aryl Fluorides." J. Flourine Chem. 21. pp 385-392 (1982)). Thus, when the trimethyl substituted iodonium ylide (10b) reaction was conducted in a deuterated solvent (e.g. DMF-d&7)

GC/MS analysis showed the presence of deutereomesitylene (Figure 4) in the product mixture indicating a radical channel competing with the nucleophilic substitution reaction.

The whole microsystem was dipped in a cooling bath (T° C.). A solution of o-dibromobenzene (0.27 M) in THF (flow rate: 6 mL/min, 1.62 mmol/min) and a solution of n-BuLi (1.5 M) in n-hexane (flow rate: 1.2 mL/min, 1.8 mmol/min) were introduced to the first T-shaped mixer M1 (inner diameter: 250 μm) by using syringe pumps. The resulting solution was passed through the microtube reactor R1 and was introduced to the second T-shaped mixer M2 (inner diameter: 500 μm). The solution was quenched with undiluted methanol (MeOH) (flow rate: 6 mL/min) and was introduced to the M2. The residence time of the tube reactor R1 (inner diameter: 500 μm, length=L cm) was X second. The residence time of the tube reactor R2 (inner diameter: 1,000 μm, length=50 cm) was 1.78 second. After finishing the reaction, an aliquot of the product solution was taken (15 sec) and was analyzed by GC (column, CBP1; 0.25 mm.x.25 m; initial oven temperature, 50° C.; rate of temperature increase, 10° C./ min).

This, at 60-62° C., was sparged with HBr gas for about 10 minutes then HBr was saturated with Br2 gas, before entering the DPE, by passing the HBr through a flask containing 18.5 mL Br2. The flask containing the Br2 was held in a water bath at room temperature. The HBr flow rate was about 100-200 mL/min. After about 2.5 hours all of the Br2 had been evaporate from its flask. The HBr flow was then stopped. The system was then purged with N2 for 30 minutes and then the DPE reaction mixture was poured into 300 mL water and stirred well. A sample of the organic phase was analyzed by GC using dibromomethane as solvent. GC analysis was on a 15 meter DB-5 column operated at 40° C., hold 2 min., then heated at 10° C. per min. to 300° C.

This was heated at 65° C. and HBr (250 mL/min) was sparged in for 30 minutes. The mixture was light yellow in color and not all the Fe had dissolved. The feed of HBr was adjusted so that it passed first into a flask containing 41.7 g of Br&2 and

then into

the DPE mixture. The HBr flow was maintained at 240-250 mL/min. and the reactor containing the DPE was held at 62-66° C. After 3.7 hours all bromine had been evaporated by the HBr gas. HBr flow was continued for about 5 minutes and then the mixture was purged with N2 for about 10 minutes. The water trap was virtually colorless meaning that it contained <10 ppm Br2. A sample of the reaction mixture were taken for NMR and GC analyses. The remainder were poured into water-containing about 4 mL of concentrated HCl. Much of the Fe powder remained unreacted. The pale yellow organic phase was phase separated, washed with water, and dried over CaCl2. The results of GC analysis, carried out as described in Example 1, are summarized in Table 2.

Copper (I) iodide (10 mg, 0.05 mmol, 5 mol percent), anhydrous fine powder potassium phosphate (425 mg, 2.0 mmol) and 2phenylphenol (34 mg, 0.2 mmol, 20 mol percent) were put into a screw-capped test tube with a Teflon septum. Anhydrous toluene (1.0 mL), bromobenzene (105 μL, 1.0 mmol) and n-hexylamine (158 μL, 1.2 mmol) were added by microsyringe at room temperature under air atmosphere. The reaction mixture was heated at 100° C. for 22 hours. The reaction mixture was then allowed to reach room temperature. Diethyl ether (2 mL), water (2 mL) and dodecane (internal standard, 227 μL) were added. The organic layer was analyzed by GC to give 33percent GC yield of N-phenylhexylamine.

Conditions & References 43 : EXAMPLE 43 n-Butyl-lithium (1.5M in hexane, 26 ml) was added dropwise to a stirred solution of a portion (7.3 g) of the bromobenzene so obtained in THF (70 ml) which had been cooled to -78° C. The mixture was stirred at -78° C. for 15 minutes. DMF (4.6 ml) was added and the mixture was allowed to warm to ambient temperature. The mixture was poured into a saturated aqueous ammonium chloride solution and extracted with diethyl ether. The organic phase was washed with brine, dried (MgSO4) and evaporated. The residue was purified by column chromatography using methylene chloride as eluent. There was thus obtained 4-(2-methyl-1,3-dioxolan-2-yl)benzaldehyde (3.5 g, 60percent) as a liquid.

Conditions & References 15.A : Preparation of the t-hydroxy-2 phenyl-1-r-(piperidino-1)-1 cyclohexane of formula: STR37 A) The Grignard reagent resulting from the action of 48.9 g (0.3M) of bromobenzene on 8.75 g (0.35M) of magnesium in the form of turnings is prepared in 300 ml of anhydrous ether. To it is added 19.6 g (0.2M) of cyclohexanone dissolved in 300 ml of anhydrous ether. Stirring takes place for 3 h on the reflux condenser and the complex is decomposed by a cold, saturated NH4 Cl solution and then, after settling, the liquids are extracted with ether (3*200 ml). The ethers are dried (Na2 SO4) and evaporated in vacuo to give a yellowish solid which, after two crystallizations in petroleum ether, give 25 g of white 1-phenyl-cyclohexanol melting at 60° to 61° C.
