Platinum complexes bearing bulky N-heterocyclic carbene (NHC) ligands, i.e., [Pt(IPr*)(dvtms)] (where, IPr* = 1,3-bis2,6-bis(diphenylmethyl)-4-methylphenyl}imidazol-2-ylidene) and [Pt(IPr*OMe)(dvtms)] (where, IPr*OMe = 1,3-bis2,6-bis(diphenylmethyl)-4-methoxyphenyl}imidazol-2-ylidene, dvtms = divinyltetramethyldisiloxane) catalyse nearly quantitatively and highly or completely the selective hydrosilylation
带有大体积N-杂环卡宾(NHC)配体的铂络合物,即[Pt(IPr *)(dvtms)](其中IPr * = 1,3-双2,6-双(二苯基甲基)-4-甲基苯基}咪唑-2-亚烷基)和[Pt(IPr * OMe)(dvtms)](其中IPr * OMe = 1,3-双2,6-双(二苯甲基)-4-甲氧基苯基}咪唑-2-亚基, dvtms =二乙烯基四甲基二硅氧烷)几乎定量且高度或完全催化末端烯烃以及末端或内部乙炔的选择性氢化硅烷化。
