On the reactivity of 1,1,1-trichloroethanal (chloral) with pyrroles (short communication)

Abstract

Reactions of pyrroles with chloral yield 1:1 and 2:1 condensation products depending on the strength of acidic catalysis and on the substituents of the pyrrole ring. Formation of a 10-dichloromethylidenebiladiene-ac in low yields is observed when two equivalents of dipyrrin-1-on are condensed with one mol of chloral.
