Reactions of halogenomethanes in the vapour phase. Part 1. Reactions of chloroform with pyrrole and methylpyrroles at 550 °C
Abstract
Chloroform reacts with pyrrole and with some methylpyrroles (2)–(9) in the vapour phase at 550 °C using a continuous-flow method to give high yields (71–92%) of chloro- and chloromethyl-pyridines (10)–(33) formed by ring expansion.
