Abstract

Phosphorus compound prepared by reaction of triphenylphosphine with trichloroisocyanuric acid was found to be applied to chlorination of nitrogen-containing π-deficient heteroaromatics. As self-decomposition of the chlorinating reagent hardly proceeds, the reagent is more useful than phosphorus compound prepared by triphenylphosphine and N-chlorosuccinimide.
