The chromium(IV) triamidoamine complex [Cr(N3N)Cl] (1; (N3N)3- = ((SiMe3NCH2CH2)3N)3-) reacts with LiR (R = Me, n-Bu) in THF to give selectively the remarkably stable, green chromium(IV) alkyls [Cr(N3N)R] (2, R = Me; 3, R = n-Bu), which have a d2 high-spin electronic configuration and feature, according to 1H and 13C NMR spectroscopy, pseudo-C3v symmetry in solution. Compounds 2 and 3 are the first
铬(IV)triamidoamine络合物[CR(N 3 N)CL](1 ;(N 3 N)3 - =((森达3 NCH 2 CH 2)3 N)3 - )与LIR(R =我反应,n- Bu)在THF中生成选择性稳定的绿色铬(IV)烷基[Cr(N 3 N)R](2,R = Me; 3,R = n -Bu),其中ad 2高-自旋电子结构和特征,根据1 H和13 C NMR光谱,伪C 3v溶液中的对称性。化合物2和3是通过单晶X射线晶体学表征的铬(IV)的第一个甲基和正丁基配合物。
