Highly Selective Generation of Urethanes from Amines, Carbon Dioxide and Alkyl Chlorides
McGhee, William D.,Pan, Yi,Riley, Dennis P.
, p. 699 - 700 (1994)
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.
