✦ Synopsis

Pseudourea-Mediated Dehydration of Tertiary and Benzylic Alcohols.

-An efficient method for the dehydration of benzylic or tertiary alcohols is presented involving the copper-catalyzed formation of a pseudourea intermediate from alcohol and dicyclohexylcarbodiimide which undergoes subsequently elimination of dicyclohexylurea to furnish the corresponding olefins. The reaction proceeds at room temperature or under gentle warming, while allylic and secondary alcohols require elevated temperatures. The method does not satisfactorily proceed with primary alcohols. -(MAJETICH, GEORGE;
