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}(C![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif) C–Ph)(CO)(PtBu2H)(Br)] is promoted by bromide abstraction and is reversed by adding NnBu4Br.
C–Ph)(CO)(PtBu2H)(Br)] is promoted by bromide abstraction and is reversed by adding NnBu4Br.
