The selective electrochemical oxidation of heteroatom compounds having two different types of electroauxiliaries, i.e. silicon and tin on the same α carbon has been achieved. The C-Sn bond was cleaved selectively and a nucleophile was introduced. The second oxidation of the compound thus obtained gave rise to the cleavage of the C-Si bond and the introduction of a second nucleophile. The present study indicates the feasibility of the redox potential based strategies using electroauxiliaries.

化学氧化。C-Sn键被选择性断裂并引入了一个亲核试剂。然后对所得化合物进行第二次氧化,导致C-Si键断裂并引入了第二个亲核试剂。本研究表明,利用电辅助基团进行基于氧化还原电位的策略是可行的。
