Reactions of 2-Cyclohexen-1-ones and Cyclohexane-1,3-diones with Chloro Methylene Iminium Salts

Article abstract of DOI:10.1021/jo00389a016

Products are isolated and pathways established for the reactions of cyclohexane-1,3-diones with Vilsmeier reagents.Similarities between those reactions and the reactions of some 2-cyclohexen-1-ones with Vilsmeier reagents are demonstrated.The pathways proposed allow rationalization of products formed by the action of Vilsmeier reagents on a variety of cyclic and acyclic ketones.
