摘要：

We have measured the rates of cleavage by a 4:3 v/v mixture of acetic acid and aqueous sulphuric acid at 50.2* of a series of X·C 6H4·SiMe3 compounds in which X is a positively charged group. The results, which are consistent with those obtained for nitration, are discussed in terms of strong inductive electron withdrawal by the positive poles, enhanced by (p → d)π, bonding in the case of the PMe3,+ and, to a lesser extent, in that of the p-AsMe3+ group.
