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
三正丁基膦和二硫化碳之间的两性离子加合物在中性条件下与二当量的乙二酸二甲酯和乙二酸二乙酯,二苯甲酰基乙炔和苯甲酰基丙炔酸甲酯反应,得到新型的结晶的含二硫醇的磷酰基化物。X射线结构,光谱和化学性质均显示它们通过离域化得到显着稳定。
