The one-pot reaction of tetra-substituted cyclopropyl benzyl bromide with tris(trimethylsilyl)methyllithium (TsiLi) and carbon disulfide resulted in 3-(4-((((trimethylsilyl)ethynyl)thio)methyl)phenyl)cyclopropane-1,1,2,2-tetracarbonitrile (3) and 3-(4-((trimethylsilyl)methyl)phenyl)cyclopropane-1,2-dicarbonitrile (4) in excellent yield. The reaction in the absence of carbon disulfide yielded 3-(4-(2,2,2-tris(trimethylsilyl)ethyl)phenyl)cyclopropane-1,1,2,2-tetracarbonitrile (5) in excellent yield at 0°C to room temperature. All structures were characterised by IR, ¹H NMR, and ¹³C NMR spectroscopies. The reaction mechanisms are discussed.

四取代环丙基苄基溴与三（三甲基甲硅烷基）甲基锂（TsiLi）和二硫化碳的一锅反应生成3-（4-（（（（（三甲基甲硅烷基）乙炔基）硫代）甲基）苯基）环丙烷-1,1 ，2，2-2-四腈（3）和3-（4-（（三甲基甲硅烷基）甲基）苯基）环丙烷-1，2-二腈（4）具有优异的产率。在不存在二硫化碳的情况下，该反应在0℃下以优异的产率生成了3-（4-（2,2,2-三（三甲基甲硅烷基）乙基）苯基）环丙烷-1,1,2,2-四腈（5）到室温。所有结构通过IR，¹ H NMR和¹³ C NMR光谱学表征。讨论了反应机理。
