Abstract
The methyl groups of the pyrroles Ia and IIa react with sulphuryl chloride to give dichloromethyl derivatives which hydrolyze to aldehydes. The pyrrole Ia also forms a trichloromethyl derivative which hydrolyzes to the corresponding acid. Alkaline decarboxylation of the latter gives opsopyrrole-dicarboxylic acid, IVa.Keywords
