Die Synthese von Aldehyden und Ketonen mit Amidchloriden und VILSMEIER‐Reagenzien

Abstract
The constitution of amide chlorides and reaction products of amides with phosphoroxychloride is discussed. Based on infrared spectra and reaction behaviour an ionized constitution is proposed. The mechanism of VILSMEIER's aldehyde synthesis is studied. Under certain conditions this reaction can be extended to the synthesis of ketones.
