Pyrrole

The Vilsmeier reaction is an alternative to Friedel-Crafts acylation and avoids the use of strong Lewis acids such as AlCl 3 This method is particularly useful for formylation because it works well with Me 2 NCHO (DMF) instead of dimethylacetamide to add a formyl (CHO) group rather than a methyl ketone The reaction can be broken down into three stages: formation of an iminium cation
