Two new titanium complexes of the general type Ti(η5:η1-C5H4SiMe2NCH2CH2X)Cl2 (X = NMe2 OMe), containing a tridentate ligand, were prepared by reaction of Ti(η5-C5H4SiMe2Cl)Cl3 with the lithium amide Li(NHCH2CH2X) (X = NMe2, OMe). The 1HNMR chemical shifts for the protons of the ethylene link were found to vary considerably as a function of the temperature, indicating the presence of an equilibrium
的一般类型的两个新的钛络合物的Ti(η 5:η 1 -C 5 ħ 4森达2 NCH 2 CH 2 X)氯2(X = NME 2 OME),含有三齿配体,是由钛的反应而制备( η 5 -C 5 H ^ 4森达2 Cl)的氯3与氨基化锂的Li(NHCH 2 CH 2 X)(X = NME 2,OME)。在1发现乙烯键的质子的HNMR化学位移随温度的变化而显着变化,表明配体的三键和二齿键合模式之间存在平衡。Ti的单晶X-射线结构分析(η 5:η 1 Ç 5 ħ 4森达2 NCH 2 CH 2 OME)氯2显示,该甲氧基函数不是分子内的固态协调。
