Reversible Insertion of Unactivated Alkenes into Silicon(II)-Tin Bonds

摘要

The migratory insertion of alkenes is one of the most fundamental processes in organometallic chemistry and thus plays a crucial role in many catalytic processes, such as polymerization, 1,2-addition reactions and Heck-type reactions. In many cases, the insertion reaction is reversible, It and a key step in catalysis is the formation of alkenes through a β-hydride elimination from alkyl transition-metal compioxes.
