Acylisocyanates amides

Amide—> Isocyanate. A general procedure for the conversion of amides into acylisocyanates" provides a route to these compounds more convenient than the reaction of acid chlorides with silver cyanate. In the example formulated a mixture of u-chloroucelamide ami 100 ml. of ethylene dichloride is chilled to about 2" and timiH u/hiia D.6 mala of oxalvl uhlorldo li added all at on c. The mixture I removed... [Pg.388]

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... [Pg.9]
