S. Kotachi et al., RUTHENIUM COMPLEX-CATALYZED SYNTHESIS OF CARBAMATES BY DEHYDROGENATIVE REACTION OF FORMAMIDES WITH ALCOHOLS, Catalysis letters, 19(4), 1993, pp. 339-344
In the presence of a catalytic amount of RuCl2(PPh3)3, various alkyl N
-arylcarbamates are obtained in 23-82% yields by dehydrogenative react
ion of N-aryl substituted formamides with alcohols. The present reacti
on offers an alternative method for phosgene- and carbon monoxide-free
synthesis of carbamates.
