Abstract

Abstract The addition reaction of triphenylphosphine to ethyl phenylpropiolate in the presence of strong CH-acids. such as Meldrum's acid, N,N′-dimethylbarbituric acid or indane-1,3-dione leading to highly functionalized 1,4-diionic organophosphorus compounds is reported. The stable crystalline phosphorus betaines were characterized by 1H, 13C and 31P nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry and elemental analysis.
