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.
钨 - 铂 μ - 碳化物配合物[WPt(μ - C)Br(CO)₂(PPh₃)₂(Tp*)](Tp* = 氢三(二甲基吡唑 - 1 - 基)硼酸盐)的溴化物和膦配体都能轻易发生取代反应,从而得到一系列多样的 μ - 碳化物配合物,包括[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]和[WPt(μ - C)(bipy)(CO)₂(PPh₃)(Bm)(Tp*)],其中大部分已通过结构表征。
