Reagent for formylating
Vilsmeier Reagent common way for formylating arenes, and heterocycles via Vilsmeier–Haack reaction. It is a white hygroscopic powder, that is shelf-stable. The formylation process is general for all activated aromatic systems (e.g. pyrene, anthracene, azulene, ferrocene, and N, N-dimethylaniline) and electron-rich heterocyclic systems (e.g. thiophenes, indoles, furans, and pyrroles). However, simple aromatic hydrocarbons such as benzene and toluene do not react with Vilsmeier reagents.
Synonyms: Dimethylchloromethyleneammonium Chloride; (chloromethylidene)dimethylazanium chloride
