SYNTHESIS AND PROPERTIES OF NOVEL DIALKYLAMINOCARBENIUM SALTS

Novel dialkylaminocarbenium salts with metallocomplex counter ions wer e prepared by the reaction of phosgene with either DMF or tetramethylu rea in the presence of metal chlorides. Reactions of organosilicon ami des with phosgene gave corresponding carbenium salts, while organosili con ureas yielded aminoiminocarbenium salts. Dialkylaminochlorocarbeni um salts were reduced with hydrosilanes to give dialkylaminocarbenium salts and can be easily hydrolyzed to afford either amides or ureas. P athways of the reaction with water and alcohols depend on the nature o f reagent and the reaction conditions.
