一氧化碳加到[PtCl(R)(NN)](R =烃基; NN =螯合N,N-配体)上,得到中性五坐标[PtCl(R)(CO)(NN)]或阳离子四-坐标[Pt(R)(CO)(NN)] +配合物,具体取决于N,N-配体的空间拥挤。对于R-芳基,在温和条件下进行迁移插入过程,并获得相应的酰基物质。报道了五配位加合物与亲核试剂的一些反应,并描述了金属上的取代或配位一氧化碳的添加。

Abstract Different types of products can be obtained by addition of proticacids HX (X=Cl, BF 4 ) to Pt(O) species of general formula [Pt(ol)(N-N)] (ol=olefin; N-N=N,N-chelate) according to the features of the two coordinated ligands. The typical attainment of four-coordinate hydrocarbyl derivatives by insertion of the alkene into the Pt-H bond is compared with the recently reported isolation of stable
摘要将质子酸HX(X = Cl,BF 4)加入通式[Pt(ol)(NN)]的Pt(O)物种中可获得不同类型的产品(ol =烯烃; NN = N,N -螯合物)根据两个配体的特征。通过将烯烃插入Pt-H键中,典型地获得四配位烃基衍生物与最近报道的稳定的五配位氢化物的分离进行了比较。最终产物的性质也与X基团的配位能力有关。提出了添加过程的一般机制。
