Brønsted acidic ionic liquid as a metal free catalyst for the one-pot synthesis of α-aminonitriles under mild and solvent-free conditions
نویسندگان
چکیده مقاله:
An efficient, mild and environmentally friendly method was developed for the Strecker reaction to synthesize α-aminonitriles in the presence of methyl imidazolium hydrogen sulfate ([Hmim][HSO4]) as an efficient catalyst. These syntheses were performed via a one-pot three-component condensation of aldehydes (or ketones), amines, and trimethylsilyl cyanide under mild and solvent free conditions.
