2. General procedure for thereaction of benzoquinone with phenylboronic acid.
General procedure: To a solution of benzoquinone (0.5 mmol, 1.0 equiv.) and [Cp*IrCl2]2 (0.025mmol, 5percent) in dichloromethane (2 mL) was added the phenylboronic acid (0.75 mmol, 1.5 equiv.) and water (2 mL) Then the solution was stirred vigorously at room temperature for 12 h. Upon completion, the reaction was diluted with dichloromethane (5 mL) and washed with 5percent sodium bicarbonate. The layers were separated, and the aqueous layer was extracted with dichloromethane (10 X 3 mL), dried over sodium sulfate, and was evaporated to give the residue. The residue was then purified by column chromatography on silica gel (ethyl acetate / petroleumether = 1:10) to provide the corresponding product. A

3:General procedure for 2a catalyzed H2O2 oxidation of dihydroxy arenes
General procedure: To a solution of dihydroxy arene (0.34 mmol) and 2a (1.98 mg,0.0034 mmol) in THF (1.0 mL) was added H2O2 (30percent aq, 50.0 mL,0.44 mmol) at 0 C. After 5 min the starting material had completelyoxidized to the quinone product. The quinone product wasthen extracted by ether or dichloromethane, dried over anhydrous Na2SO4, and concentrated under reduced pressure to afford thedesired product. Pleasingly, the resulted quinone products werepure enough and there is no necessity for column chromatographyin most of the cases. Hide Details

Oxidation Reactions; Typical Procedure
General procedure: A solution of CAN (0.056 g, 0.102 mmoles) and sodium bromate (0.780 g, 5.17 mmoles) in H2O (3 mL) was added slowly to vigorously stirred anhydrous silica gel (5 g) that was contained in a 100 mLround-bottom flask containing a magnetic stirring bar and fitted with a rubber septum. After complete addition of the aqueous solution, stirring was continued until a free-flowing powder was obtained.CH2Cl2 (25 mL) was then added to the flask and a solution of hydroquinone 1A (220.23 mg, 2.0 mmol), in CH2Cl2 (5 mL) was added slowly to the stirred heterogeneous mixture. A condenser was attached to the flask and the reaction was heated to reflux. Disappearance of 1A was monitored by thin-layer chromatography (EtOAc–hexane, 1:4; panisaldehyde/sulfuric acid as staining agent). Upon complete disappearance of 1A (ca. 2 h), the reaction mixture was filtered through a sintered glass funnel, the solid residue was washed with additional CH2Cl2 (3 × 10 mL), and the washings were added to the filtrate. Removal of solvent from the organic solution under vacuum gave an orange solid. Radial chromatography of the crude product (EtOAc–hexane,1:9) gave 1,4benzoquinone 2A (89 mg, 82percent) as an orange solid. 85%

1:EXAMPLE 1
EXAMPLE 1 2-t-butyl hydroquinone (Ic) of 3.0 g (18 mmol) are dissolved in 50 ml of chloroform, and wherein 50 ml of 10percent hypochloride solution (6.0 g NaOCl, 80 mmol) containing 200 mg (0.59 mmol) of tetra-n-butyl ammonium are added. The solution of hypochloride had been so prepared as to be at pH 8 by using conc. hydrochloric acid, before use. The mixture reacted is stirred severely for five minutes at room temperature, then, the water and the organic layers of the reacted mixture are separated from each other, and the organic layer is washed with 180 ml of cold water. Thereafter, the organic layer having been washed is dried up by magnesium sulfate anhydrous, and chloroform is removed therefrom at reduced pressure and at 30° C., and the residue is crystallized from 10 ml of hexane. Then, 2-t-butyl benzoquinone (III c) of 2.60 g (15.9 mmol) are obtained. Yield at 88percent, m.p. at 54°-55° C. [Value in the literature: at 52°-55° C. from I. Buben and J. Pospisil, Collect Czech., Chem. Commun., 34, 1991 (1969).]

General Procedure for the Reaction of Benzoquinone with Boronic Acid
General procedure: To a solution of benzoquinone (0.5 mmol, 1.0 equiv) and [Cp*RhCl2]2 (0.025 mmol, 5 molpercent) in CH2Cl2 (2 mL) was added the boronic acid (0.75 mmol, 1.5 equiv), H2O (1 mL). Then the solution was stirred vigorously at r.t. for 10 h. Upon completion, the reaction was diluted with CH2Cl2 (3 mL) and washed with 5percent NaHCO3. The layers were separated, and the aqueous layer was extracted with CH2Cl2 (3 × 4 mL), dried over Na2SO4, and was evaporated to give the residue. The residue was then purified by column chromatography on silica gel (EtOAc–PE, 1:10) to provide the corresponding product.

Preparation of 2-tert-butyl-1, 4-benzoquinone A mixture of 2-t-butylphenol (5 mmol) and Ti-superoxide catalyst (125 mg, 20percent w/w) in acetic acid (5 ml) was heated with stirring at 50-60 C under inert atmosphere. To this reaction mixture was added aq. 30percent H202 (20 mmol) drop wise over 15 min. and heated for 1 h. The catalyst was recovered by simple filtration and 2-tert-butyl-1, 4-benzoquinone formed (97percent) was separated by chromatographic purification.Table 1: Ti-superoxide (1) catalyzed oxidation of phenols to quinines and hydroquinones with aq. 30percent H202 : a Ex.

An amber 3 dram vial was charged with o-cresol (1.47 mL, 14.00 mmol), 48 percent hydrobromic acid (0.118 mL, 1.0 mmol of hydrogen bromide), cupric bromide (156 milligrams, 0.7 mmol), water (0.45 mL, 25 mmol) and acetonitrile (2.91 mL). The vial was loaded into an aluminum block, placed inside an autoclave and pressurized with air (1000 psi). Upon heating at 65° C. for 2 hours the autoclave was allowed to cool and the product mixture was analyzed by gas chromatography. The product mixture was found to contain 4-bromo-2-methylphenol (5.5percent by weight), methyl-1,4benzoquinone (6.40percent by weight), and 6-bromo-2-methylphenol (0.6percent by weight). These product concentrations corresponded to 45 percent overall conversion of o-cresol to products with a selectivity for 4-bromo-2-methylphenol of 22 percent and a selectivity for methyl-p-benzoquinone of 40 percent.

An amber 3 dram vial was charged with m-cresol (1.46 mL, 14.00 mmol), 48 percent hydrobromic acid (0.118 mL, 1.0 mmol of hydrogen bromide), cupric bromide (156 milligrams, 0.7 mmol), water (0.45 mL, 25 mmol) and acetonitrile (2.92 mL). The vial was loaded into an aluminum block, placed inside an autoclave and pressurized with air (1000 psi). Upon heating at 65° C. for 2 hours the autoclave was allowed to cool and the product mixture was analyzed by gas chromatography. The product mixture was found to contain 4-bromo-3-methylphenol (6.2percent by weight), methyl-p-benzoquinone (15.84percent by weight). These product concentrations corresponded to 67 percent overall conversion of m-cresol to products with a selectivity for 4-bromo-3-methylphenol of 17 percent and a selectivity for methyl-p-benzoquinone of 65 percent.
