A new synthesis of pyrroles by the condensation of cyclopropenes and nitriles mediated by gallium(iii) and indium(iii) salts

Abstract

Gallium(III) and indium(III) halides were found to mediate the condensation of cyclopropenes and nitriles to give pyrrole derivatives in moderate yields. When excess nitrile was present, diazepine was also formed.
