Abstract
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 α′‐derivatives partially parallels that of the corresponding silicon derivatives in reaction with aldehydes. © 2000 John Wiley & Sons, Inc. Heteroatom Chem 11:1–5, 2000

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 α′‐derivatives partially parallels that of the corresponding silicon derivatives in reaction with aldehydes. © 2000 John Wiley & Sons, Inc.
