and chemistry of the complex [PtMe2(bebipy)], 1, where bebipy = 4,4′-bis(ethoxycarbonyl)-2,2′-bipyridine, are described. Complex 1 reacted with HCl to give [PtClMe(bebipy)] and [PtCl2(bebipy)], and all of these platinum(II) complexes gave π-stacking in the solid state. Complex 1 reacted with X2 by trans oxidative addition to give [PtX2Me2(bebipy)], X = Br, I, OH, and the complex with X = I is characterized
描述了配合物[PtMe 2(bebipy)] 1的合成和化学性质,其中bebipy = 4,4'-双(乙氧基羰基)-2,2'-联吡啶。配合物1与HCl反应生成[PtClMe(bebipy)]和[PtCl 2(bebipy)],所有这些铂(II)配合物在固态下均产生π堆积。配合物1与X 2通过反式氧化加成反应生成[ PtX 2 Me 2(bibipy)],X = Br,I,OH,且具有X = I的配合物的结构确定为[PtI 2 Me 2(bibipy) )]。1.5I 2。综合大楼1通常通过反式氧化加成与RX反应,得到[PtXRMe 2(bibipy)],R = Me,X = I;R = CO 2 Et,X = Cl; R = CH 2 CO 2 H,X = Br; R = CH 2 -4-C 6 H 4 -CO 2 H,X = Br; R = CH 2 -4-C 6 H 4 -CH 2 CO
