摘要

A range of electrophiles react with 2-(trimethylsilyl) prop-2-enylzinc chloride, which is prepared by sequentially treating 2-bromo-1-trimethylsilylprop-2-ene with ButLi and then zinc chloride. The addition of transition metal catalysts can alter the reactivity of the organometallic compound from prop-2-enylation to prop-1-en-2-ylation.
