The rates of cleavage at 50° by a mixture of ethanol (5 vol) and aqueous perchloric acid (2 vol) of the aryl-SnMe3 bonds of p-[(Me3Si)xMe(3−x)Si]C6H4SnMe3 compounds relative to that of phenyltrimethylstannane have been found to be 0.93 (x = 0), 1.31 (x = 1), 1.67 (x = 2) and 1.76 (x = 3). The increase in rate with the increasing magnitude of x can be attributed to inductive and hyperconjugative electron

高氯酸水溶液(2份体积)的混合物在50°时的裂解速率为p -[(Me 3 Si)x Me (3- x) Si] C的芳基-SnMe 3键已发现相对于苯基
三甲基锡烷的6 H 4 SnMe 3化合物为0.93(x = 0),1.31(x = 1),1.67(x = 2)和1.76(x = 3)。速率随x幅度的增加而增加,可归因于从SiSi键释放的感应和超共轭电子。
