of the insertion of sulfur dioxide into the aryl carbon—tin bond of a species of 3- and 4-substituted phenyltrimethyl stannanes in anhydrous methanol has been conducted. The reaction is cleanly second order in this solvent (first order in each of stannane and sulfur dioxide) and the second order rate constants show an excellent correlation with σ+, indicating an electrophilic insertion reaction. The
进行了将二氧化硫插入无水甲醇中的3-和4-取代苯基三甲基锡的种类的芳基碳-锡键中的动力学研究。在该溶剂中反应完全是二阶的(锡烷和二氧化硫各为一阶),二阶速率常数与σ +表现出极好的相关性,表明发生了亲电插入反应。低p值和对插入速率的正盐效应表明具有四个中心极性的S E i过渡态。二氧化硫位于亲电反应性系列中,CH 3,COOH
