Abstract

Halogenated pyrroles have been synthetic targets for over a century. 2, 3, 4, 5- Tetrahalopyrroles were first reported in the 1880s; 1-3 by 1934 Fischer had catalogued more than 60 simple ring-halogenated derivatives in Die Chemie des Pyrrols. 4 The first definitive preparation of an otherwise unsubstituted 3, 4-dihalopyrrole was due to Fischer, who synthesized 3, 4-dichloropyrrole by saponification and double decarboxylation of 3, 4- ...
