4.2.3. 2-Chlorobenzonitrile (Table 2, entry 2) To a 25 mL round-bottom flask equipped with magnetic stirrer were added 2-chlorobenzaldehyde oxime (311 mg, 2 mmol), cupric acetate (Cu(OAc)2) 36 mg (0.2 mmol) and acetonitrile(5 mL). The mixture was heated to reflux for 1.5 h. After cooling to room temperature, the solution was directly evaporated to dryness and the residue was purified by column chromatography on silica gel (ethyl acetate/n-hexane=1:10) to give 2-chlorobenzonitrile as a white solid (261 mg, 95percent). 1H NMR (500 MHz, CDCl3): δ 7.39 (m, 1H), 7.56 (m, 2H), 7.69 (m, 1H) Data are in good agreement with the literature.24 With copper diacetate, acetonitrile, Time= 1.5h, Reflux Ma, Xiao-Yun; He, Ying; Lu, Ting-Ting; Lu, Ming; Tetrahedron; vol. 69; nb. 12; (2013); p. 2560 - 2564 View in Reaxys

General procedure for the preparation of nitriles General procedure: PEG-SO2Cl (0.15 mmol, 326 mg) was added to a stirred solution of aldoxime (1.0 mmol) in freshly distilled dichloromethane (10 mL), and the reaction mixture stirred at reflux temperature for the given time in Table 2. After completion of the reaction (monitored by TLC), the solution was concentrated by rotary evaporation and diluted with slow addition of an excess of cold ether with vigorous stirring. The precipitate was filtered through a fritted funnel, washed with ether, and dried well to furnish the PEG-bound sulfonic acid in excellent yield and then converted into the PEG-SO2Cl for the recycling. The filtrate was concentrated in a rotary evaporator, and finally the crude product was purified by column chromatography eluted with 10–20percent ethyl acetate in hexane for their structure analysis.

Synthesis of nitriles; general procedure General procedure: An aldehyde (2 mmol), CuO (0.1 mmol), NH2OH·HCl (3 mmol),NaOAc (3 mmol) and acetonitrile (6 mL) were added to a 25 mL round bottom flask equipped with magnetic stirrer. The mixture was heated to reflux for 3–10 h. After cooling to r.t., acetonitrile was distilled off under reduced pressure. Water (15 mL) and ethyl acetate (30 mL) were added to the reaction mixture, and the organic layer was washed with saturated aqueous sodium bicarbonate (1 × 15 mL) and water(1 × 15 mL).

General procedure: Preparative electrolysis experiments were performed using 263 APotentiostat/Galvanostat (Princeton Applied Research, USA). 0.1 MNaClO4–CH3CN solution (10 mL) containing aldehydes (1 mmol),TEMPO (0.1 mmol), HMDS (2.5mmol) and AcOH (2.5mmol) was electrolyzedwith stirring in an undivided cell (30 mL) equipped with twoplatinum sheets as anode (1.5 cm2) and cathode (3.0 cm2) respectivelyat a constant potential of 1.5 V vs Ag/Ag+ (0.1MAgNO3 in acetonitrile).The electrode separation was 1 cm. When the reaction was finished,10mL of saturatedNa2SO3 solution was added into the reactionmixtureand stirred for 15 min. Then the mixture was extracted with CH2Cl2(20 mL × 3). The organic layer was dried with anhydrous Na2SO4 andconcentrated in a rotary evaporator. The productswere obtained via purificationof column chromatography and their structures were confirmedby 1H NMR, 13C NMR and MS. NMR was performed on a BrukerAvance III spectrometer. GC-MS was performed on the Thermo TraceISQ instrument with TG 5MS capillary column.

The dark reaction mixture fainted in colour at the end of reaction. The excess of ammonia was removed by stirring at 90 °C. Then, O,O-diethyl dithiophosphoric acid (2) (1.5 mmol) was added and the reaction mixture was stirred at 90 °C for 2-4 h (Table 2). After completion of the reaction (monitored by TLC), the mixture was cooled to r.t. The product thus precipitated was filtered, washed with aqueous sodium thiosulfate solution followed by water and dried under reduced pressure to give pure primary thioamides 3 (Table 2).

3.4.4 Diazotization–halogenation to aryl chlorides 7 arenediazonium camphorsulfonate General procedure: Camphorsulfonic acid (3.0 mmol), tert-butyl nitrite (3.0 mmol), benzyltriethylammonium chloride (5.0 mmol), and catalytic amounts of copper chloride (1 mol percent) were added to an acetonitrile solution (30 ml) of aniline (2.5 mmol). The reaction mixture was stirred at 60 °C for 24 h (Tables 1 and 2). The evolution of N2 was immediately observed. The solvent was removed by rotary evaporator after completion of the reaction (confirmed by β-naphthol test and TLC). The crude residue was purified via column chromatography by using hexane/dichloromethane as the eluting solvent. Physical and 1H NMR data were identical to those of a commercially available sample of analytical purity.

Conditions & References General procedure for cyanation reaction of aryl halides with K4[Fe(CN)6] under microwave irradiation General procedure: A mixture of the aryl halide (1 mmol), K4[Fe(CN)6]*3 H2O (0.22 mmol, 92.9 mg), TBAB (1 mmol, 322.4 mg), palladacycle catalyst (0.5 mmol percent, 4.7 mg), and K2CO3 (1 mmol, 138.2 mg) was added to DMF (3 mL) in a round-bottomed flask equipped with a condenser and placed into the Milestone microwave. Initially using a microwave power of 600 W the temperature was ramped from room temperature to 130 °C, this taking approximately 1 min, and then held at this temperature until the reaction was completed. During this time, the power was modulated automatically to keep the reaction mixture at 130 °C. The mixture was stirred continuously using an appropriate magnet during the reaction. After the reaction was completed, the mixture was cooled to room temperature and diluted with water (30 ml) and ethyl acetate (30 ml). The organic layer was dried over MgSO4, filtered, and the solvent was evaporated using rotary evaporator. The residue was purified by silica gel column chromatography or by recrystallization using ethanol and water. The products were characterized by comparing their mp, IR, 1H, 13C NMR spectra with those found in the literature.

The above-described catalyst suspension is then added and the mixture is heated for 5 hours under reflux. At 23° C., the mixture is admixed with 100 ml of ethyl acetate. The organic phase is separated off, evaporated on a rotary evaporator and fractionally distilled under reduced pressure. This gives 31.6 g (75percent of theory) of 2-cyano-4'-methylbiphenyl (bp. 140° C./1.0 mbar; mp. 50° C.). Patent; Hoechst Aktiengesellschaft; US5756804; (1998); (A1) English View in Reaxys Cl
