摘要

The reaction of 2-(trimethylsilyl) phenylboronic acid with alkynes in the presence of a rhodium catalyst affords benzosilole derivatives. The arylvinylrhodium intermediate undergoes formal substitution at a silicon center, resulting in the cleavage of a robust silicon− methyl bond in the trimethylsilyl group.
