Reactions at the β-carbon of anionic tungsten acetylide complexes: Ion pairing, vinylidene formation, and CO2 binding

Addition of CO2 to the β-carbon of Li[fac(OC)3(dppe)WC≡CR] (R = Me, n -Bu) followed by methylation yields vinylidene products, mer-(OC)3(dppe)W= C=C(R)CO2Me. Ion-pair formation at the β-carbon may act as a kinetic mediator in this system. We also report syntheses of mer-(OC)3(dppe)W=C=CRR′ complexes, including the parent C=CH2 derivative.
