Abstract
Carbamic esters may be prepared directly by the reaction of carbon dioxide, epoxides, and primary or secondary aliphatic amines. For example, the monocarbamic ester of the 1,2-diol derived from epoxycyclohexane was obtained in good yield when epoxycyclohexane was reacted with amine in an atmosphere of carbon dioxide. The reaction between an epoxide and a carbamic acid or its ammonium salt, formed from carbon dioxide and amine, is proposed as a reasonable mechanism for the formation of the carbamic ester.Keywords
