Abstract
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.
