Carbon monoxide adds to [PtCl(R)(N-N)] (R=hydrocarbyl group; N-N = chelating N,N-ligand) to afford neutral five-coordinate [PtCl(R)(CO)(N-N)] or cationic four-coordinate [Pt(R)(CO)(N-N)]+ complexes, depending on the the sterical crowding of the N,N-ligand. For R-aryl, a migratory insertion process follows under mild conditions and the corresponding acyl species are obtained. Some reactions of the five-coordinate
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。
