✦ Synopsis

Phosphorylated enaminones can be obtained by the reaction of enaminone dianions with diphenylphosphinoyl chloride. In most cases, the reaction gave a mixture of monosubstituted and disubstituted compounds. Disubstituted compounds show an interesting NMR spectrum. In fact, the methine proton appears as a broad signal whose chemical shift varies with concentration. The chemistry of the ␣Ј-derivatives partially parallels that of the corresponding silicon derivatives in reaction with aldehydes.
