Reactivity of [MCl(η³-allyl)(CO)₂(N−N)] Complexes (M = Mo, W; N−N = bipy, phen) toward Alkyl and Acetylide Anions

Abstract

The reactions of [MoCl(η3-allyl)(CO)2(N−N)] (N−N = bipy, phen) and of the related tungsten complexes with MgR2 reagents (R = Me, Et, Bz) gave as single products the new alkyls [M(R)(η3-allyl)(CO)2(N−N)] (3−9), which have the alkyl and allyl groups in trans positions. Related alkynyls [M(C⋮CR)(η3-allyl)(CO)2(N−N)] with R = Ph, SiMe3, H (10−15) were obtained similarly employing alkaline acetylides.
