Unprecedented reversible coupling of alkynyl and phosphide ligands on a dinuclear platinum framework.
The reductive coupling of the bridging phosphide and the adjacent [sigma]-alkynyl moieties in [Pt2(mu-P(t)Bu2){mu,eta1:eta2-C(Ph)CH2}(C[triple bond]C-Ph)(CO)(P(t)Bu2H)(Br)] is promoted by bromide abstraction and is reversed by adding N(n)Bu4Br.
