在铑催化剂存在下，2-（三甲基硅基）苯基硼酸与炔反应得到苯并噻咯衍生物。芳基乙烯基铑中间体在硅中心进行形式取代，导致三甲基甲硅烷基中的稳健硅-甲基键的裂解。
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.
