The effect of metal–metal bonding on the regiospecificity of nucleophilic addition to carbonyl ligands in complexes of the type [(OC)4M(µ-PPh2)2Pt(PR3)] and analogues

Abstract

Regiospecific nucleophilic addition of PhLi to the equatorial CO of [(OC)₄[graphic ommitted]′L_x] is considered to be a direct consequence of M → M′ bonding rather than due to steric effects, and contrasts with the lack of reactivity of PhLi with cis-[(OC)₄M(PR₃)₂] and the general observation that in octahedral systems a CO trans to CO (as opposed to PR₃) is more susceptible to nucleophilic addition.
