Vilsmeier Reactions of 2-Alkyl-2-cyclohexen-1-ones: A Novel Route to Dihydrobenzaldehydes, the Formation of Allyl Alcohols as By-products, and the X-ray Crystallographic Structure of 3-Chloro-2-methyl-2-cyclohexen-1-ol

A series of 2-alkyl-2-cyclohexen-1-ones on reaction with 4-formylmorpholine in the presence of POCl3 gave the corresponding 3-alkyl-2-chloro-5,6-dihydrobenzaldehydes, usually accompanied by significant amounts of allylic alcohols as by-products.The structure of the allylic alcohol 12a from 2-methyl-2-cyclohexen-1-one was confirmed by X-ray analysis.The allylic alcohols are probably formed by addition of oxyanions to Vilsmeier intermediates.

Various 2-cyclohexen-1-ones underwent formylation on treatment with formamides and POCl3 at 20 deg C.Two distinct reactivity patterns were found: type A, in which mono-, di-, or triformylated olefins or benzenes are formed, and type B, in which a 3-methyl
