Abstract
N-(2-Alkeny1) amides are converted to imino chlorides or imino chloride hydrochlorides with phosphorus (V) chloride or phosgene, respectively. These products, on treatment with a tertiary amine, give 4-pentenenitriles via a Claisen-type rearrangement. Since intermediates have not been isolated, it is not known whether the reaction proceeds through the formation of a discrete ketenimine or whether the process is a concerted one. The reaction appears ...
