An improved method for the preparation of nitriles and thiocyanates from halides with benzyltrimethylammonium salts and a convenient preparation of both aliphatic and aromatic nitriles from aldehydes through N,N,N-trimethylhydrazonium salts have been reported. Nitriles can be easily converted into amidines with ammonium halides . Acylisocyanates can be conveniently prepared from amides with oxalyl chloride . A simple preparation of alkyl and aryl carbamates with N-carbonylsulfamic acid...
