Reactions of various XYP(NSiMe3)N(SiMe3)2 compounds with the tetrachlorides of Ti, Zr, and Sn afford aminoimino phosphate and phosphonate chelates XYP(NSiMe3)2[M] of the respective metals. The X-ray structures of 1 (X=Y=MeO, [M]=TiCl3·MeCN), 2 (X=Y=MeO, [M]=ZrCl3·MeCN), 9 (X2=(CF3CS)2, [M]=TiCl3) and 11 (X=Cl, Y=CCl3, [M]=TiCl3) have been determined. In addition to the monochelates, bischelates [X2P(NSiMe3)2]MCl2
各种XYP(NSiMe 3)N(SiMe 3)2化合物与Ti,Zr和Sn的四氯化物反应,得到相应金属的氨基亚氨基磷酸酯和膦酸酯螯合物XYP(NSiMe 3)2 [M]。的X射线结构1(X = Y =的MeO,[M] =的TiCl 3 ·MeCN中),2(X = Y =的MeO,[M] =的ZrCl 3 ·MeCN中),9(X 2 =(CF 3 CS)2,[M] = TiCl 3)和11(X = Cl,Y = CCl 3,[M] = TiCl 3)已经确定。除单螯合物外,双螯合物[X2 P(NSiMe 3)2 ]的MC1 2,5(X =环氧乙烷,M = Sn)和10(X 2 =(CF 3 CS)2,M = Ti)的已通过改变化学计量合成。描述了5的X射线结构。
