Abstract

Abstract: The mechanism of the a-side-chain chlorination with molecular chlorine in dichloromethane or chloroform solution at low temperatures and in the dark of polysubstituted a-methylpyrroles 1-4 ha5 been investigated with regard to the nature of the reagent and to the fate of the attacking as well as the substitucnt halogen in the reaction products. Careful product analysis was carried out by radiochemical measurements ( ...
