Abstract

The conversion of trichloromethyl and tribromomethyltriazoles to the corresponding carboxamide derivatives is described. The trihalomethyl analogs are straightforward to make and react readily with a range of amines to produce carboxamides. The strategy avoids the problems of decarboxylation associated with the use of triazole acids.
