The synthesis and structural characterization of a series of novel platinum(0) complexes were reported. A number of (NHC)Pt(dvtms) (dvtms = 1,3-divinyl-1,1,3,3-tetramethyldisiloxane) complexes were investigated in catalytic addition of B2Pin2 to terminal alkenes. The novel expanded ring N-heterocyclic carbene complex (7-Dipp)Pt(dvtms) showed highest performance, turnover numbers up to 3800 were achieved
报道了一系列新型铂(0)配合物的合成和结构表征。在将B 2 Pin 2催化加成到末端烯烃中时,研究了许多(NHC)Pt(dvtms)(dvtms = 1,3-二乙烯基-1,1,3,3-四甲基二硅氧烷)配合物。新型的扩展环N-杂环卡宾络合物(7-Dipp)Pt(dvtms)表现出最高的性能,实现了高达3800的周转率。用20个带有各种烷基,烷氧基,卤素,酯,酮和缩醛取代基的实施例说明了反应的范围。
