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