Unprecedented reversible coupling of alkynyl and phosphide ligands on a dinuclear platinum framework†
Abstract
The reductive coupling of the bridging phosphide and the adjacent σ-alkynyl moieties in [Pt2(μ-PtBu2){μ,η1:η2-C(Ph)CH2}(CC–Ph)(CO)(PtBu2H)(Br)] is promoted by bromide abstraction and is reversed by adding NnBu4Br.
