Abstract
Heterobi- and tetrametallic phosphoniocarbyne bridged complexes [WAu(μ-CPMe2Ph)Cl(CO)2(Tp*)]+(Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate), [W2Cu2(μ-CPMe2Ph)2(μ-Cl)2(CO)4(Tp*)2]2+and [WPt(μ-CPMe2Ph)(COD)(CO)2(Tp*)]+(COD = 1,5-cyclo-octadiene) arise from the reactions of the mononuclear terminal phosphoniocarbyne [W(CPMe2Ph)(CO)2(Tp*)]PF6with [AuCl(THT)] (THT = tetrahydrothiophene), [CuCl(SMe2)] and [Pt(nbe)3] (nbe = norbornene) in the presence of COD. The COD ligand in [WPt(μ-CPMe2Ph)(COD)(CO)2(Tp*)]+is labile and readily replaced by isonitriles to provide [WPt(μ-CPMe2Ph)(CNR)2(CO)2(Tp*)]+(R =tBu, C6H2Me3-2,4,6) with retention of the tungstaplatinacyclopropene core, the bonding within which was computationally interrogated.
