ScCl3 in tetrahydrofuran (THF) afforded the five-coordinate scandium chloride derivatives [Sc(N2TMSNpy)Cl(THF)] 1 and [Sc(N2NC2,TMS)Cl(THF)] 2 where N2TMSNpy = MeC(2-C5H4N)(CH2NSiMe3)2 and N2NC2,TMS = Me3SiN(CH2CH2NSiMe3)2. The corresponding reactions of ScCl3 with the dilithium salts of the amino N-methylated two-carbon analogue N2NC2,Me (N2NC2,Me = MeN(CH2CH2NSiMe3)2) or of the amino N-silylated
锂化二酰胺基吡啶与-胺的反应 配体具有ScCl 3 in的Li 2 N 2 TMS N py或Li 2 N 2 N C2,TMS四氢呋喃(THF)得到五配位的氯化dium衍生物[Sc(N 2 TMS N py)Cl(THF)] 1和[Sc(N 2 N C2,TMS)Cl(THF)] 2,其中N 2 TMS N py = MeC(2-C 5 H 4 N)(CH 2 NSiMe 3)2和N 2 N C2,TMS = Me 3 SiN(CH 2 CH 2 NSiMe 3)2。ScCl 3与亚乙基双锂盐的相应反应氨基N-甲基化的二碳类似物N 2 N C2,Me (N 2 N C2,Me = MeN(CH 2 CH 2 NSiMe 3)2)或氨基N-甲硅烷基化的三碳链类似物N 2 N C3,TMS (N 2 N C3,TMS = Me 3 SiN(CH 2 CH 2 CH 2 NSiMe
