  Stable η¹-Alkynyl−μ,η¹:η²-Alkenyl Complexes from the Reaction of Terminal Alkynes with Encumbered Dinuclear Platinum Compounds and Their Formyl, Methoxycarbonyl, and Hydride Derivatives

  摘要：

  The stepwise reaction of terminal alkynes with [(OC)Pt(mu-PBu2t)(2)Pt(H)((PBu2H)-H-t)]OTf yields intermediate eta(1)-alkynyl -hydride-bridged complexes, and then stable eta(1)-alkynyl/alkenyl-bridged derivatives containing an electrophilic carbonyl ligand. The latter is attacked by nucleophiles (H- and MeO-) to give a rare platinum formyl species, which is slowly converted into a stable hydride or a stable methoxycarbanyl complex.

  The reductive coupling of the bridging phosphide and the adjacent σ-alkynyl moieties in [Pt2(μ-PtBu2)μ,η1:η2-C(Ph)CH2}(CC–Ph)(CO)(PtBu2H)(Br)] is promoted by bromide abstraction and is reversed by adding NnBu4Br.

  [Pt2(μ-PtBu2)μ,η1:η2-C(Ph)CH2}(CC–Ph)(CO)(PtBu2H)(Br)]中桥联磷化物和相邻σ-炔基部分的还原偶联溴化物提取可促进该反应，并可通过添加 NnBu4Br 来逆转。
