Abstract
The tungsten–platinum μ-carbido complex [WPt(μ-C)Br(CO)2(PPh3)2(Tp*)] (Tp* = hydrotris(dimethylpyrazol-1-yl)borate) undergoes facile substitution of both bromide and phosphine ligands to afford a diverse library of μ-carbido complexes that includes [WPt(μ-C)Br(CO)2(dppe)(Tp*)], [WPt(μ-C)(NCMe)(CO)2(PPh3)2(Tp*)]OTf, [WPt(μ-C)(S2CNEt2)(CO)2(PPh3)(Tp*)], [WPt(μ-C)(bipy)(CO)2(PPh3)(Tp*)]PF6, [WPt(μ-C)(phen)(CO)2(PPh3)(Tp*)]PF6, [WPt(μ-C)(terpy)(CO)2(Tp*)]PF6, [WPt(μ-C)(CO)2(PPh3)(Bp*)(Tp*)], [WPt(μ-C)(CO)2(PPh3)(Tp*)2] and [WPt(μ-C)(bipy)(CO)2(PPh3)(Bm)(Tp*)], most of which have been structurally charcaterised.
