摘要：

The zwitterionic adduct between tri-n-butylphosphine and carbon disulphide reacts under neutral conditions with two equivalents of dimethyl- and diethyl acetylenedicarboxylate, dibenzoylacetylene and methyl benzoylpropiolate to give novel crystalline dithiole-containing phosphorus ylides. An X-ray structure, spectroscopic and chemical properties all show these to be significantly stabilised by delocalisation.
