Abstract

Generation of carbamate anions from either a primary or secondary amine, carbon dioxide and a stoichiometric amount of a pentaalkylguanidine followed by the addition of alkyl chlorides gives high yields of urethanes. ... The most important pathway towards the synthesis of polyurethanes rests on phosgenelisocyanate technology. 1 Because of the toxicity of these materials a significant effort has been undertaken to find new methods for making polyurethane materials.2 Our ...
