PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
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.
