The reaction of lithium (tert-butyldimethylsilyl)(2,4,6-tri-tert-butylphenyl)phosphide with chloroform afforded (Z)-2-(tert-butyldimethylsilyl)-2-chloro-1-(2,4,6-tri-tert-butylphenyl)-1phosphaethene. The NMR study revealed a secondary phosphine resulting from a formal insertion of a dichlorocarbene to the P-Si bond as a reaction intermediate. The reaction is specific to the reactants and substrates. The use of bromoform gave a bromosilylphosphine and a 2bromo-1-phosphaethene. A less hindered trimethylsilylphosphide afforded bis(2,4,6-tri-tertbutylphenyl)diphosphene.

(2,4,6-三叔丁基苯基)甲硅烷基磷化锂与卤仿反应

(叔丁基二甲基甲硅烷基)(2,4,6-三-叔丁基苯基)磷化锂与氯仿反应得到(Z)-2-(叔丁基二甲基甲硅烷基)-2-氯-1-(2,4,6) -三-叔丁基苯基)-1磷酸乙烯。核磁共振研究揭示了二氯卡宾作为反应中间体正式插入 P-Si 键所产生的二级膦。该反应特定于反应物和底物。使用溴仿得到溴甲硅烷基膦和 2bromo-1-phosphaethene。受阻较小的三甲基甲硅烷基磷化物得到双（2,4,6-三叔丁基苯基）二膦。
