N,N-disubstituted formamides, wherein the substituents are selected to provide formamides which have low volatility, are useful as halogenation catalysts. Such catalysts are generally less hazardous to use than typical formamide halogenation catalysts because toxic catalyst by-products are also less volatile. Methods for using such catalysts are provided.

Halogenation catalyst

The present invention provides an improved process for the production of triazoles of the formula: ##STR1## wherein Z is an optionally substituted (C.sub.6 -C.sub.10)aryl group; R is a hydrogen atom, a (C.sub.1 -C.sub.12)alkyl group, a (C.sub.3 -C.sub.8) cycloalkyl group, a (C.sub.2 -C.sub.8)alkenyl group, a (C.sub.5 -C.sub.8) cycloalkenyl group, a (C.sub.2 to C.sub.8)alkenyl group, an optionally substituted (C.sub.7 to C.sub.14)aralkyl group, a (C.sub.2 to C.sub.4)alkynoxy group, an optionally substituted (C.sub.6 to C.sub.10)aryloxy group or a hydroxy group;
