1-(Trimethylsilyl)allyl chloride prepared conveniently from 1,3-dichloropropene reacted smoothly with organocopper compounds yielding terminal alkenylsilanes, while its Grignard reactions with carbonyl compounds gave the corresponding alcohols with the regioselection depending sensitively on substrates.
Intramolecularcarbolithiation of 3-lithioxy-5-hexenyllithiums was studied. Unlike the case of 5-hexenyllithium, the cyclization of 3-lithioxy-5-hexenyllithium was very sluggish. Acceleration was observed when lithium chloride was added, suggesting that intramolecular lithioxy coordination would hinder the cyclization. Introduction of a silyl or thiophenyl group at the olefin terminus caused smooth
