| Abstract: | Four α monoalkylated products of benzyl cyanide were synthesized via rapid alkylation of benzyl cyanide in ‘dry’media under microwave irradiation coupled with PTC.Under the reaction conditions:benzyl cyanide 10 mmol,alkyl halide 11.5 mmol,tetrabutylammonium bromide 1 mmol,microwave power 240 W and microwave irradiation time 1-1.5 min.The isolated yields ranged from 79%～85%. |
