Vilsmeier reagents generated from amides and acyl halides have been found to be versatile in the organic synthesis because they have both electrophilicity and nucleophilicity. Some types of reactions under vilsmeier condition in recent years are reviewed in this paper. The paper focuse on the, acylation, chlorination, chloroformylation, aromatization, annulation and dehydration and so on.
