Green [HIPTN3N]V(THF) ([HIPTN3N]3- = [(HIPTNCH2CH2)3N]3-, where HIPT = 3,5-(2,4,6-i-Pr3C6H2)2C6H3) can be prepared in a 70-80% yield via the addition of H3[HIPTN3N] to VCl3(THF)3 in THF, followed by the addition of LiN(SiMe3)2. From [HIPTN3N]V(THF), the following have been prepared: [HIPTN3N]VN2}K, [HIPTN3N]V(NH3), [HIPTN3N]V=NH, [HIPTN3N]V=NSiMe3, [HIPTN3N]V=O, [HIPTN3N]V=S, and [HIPTN3N]V(CO). No ammonia
可以在70中制备绿色的[HIPTN3N] V(THF)([HIPTN3N] 3- = [(HIPTNCH2CH2)3N] 3-,其中HIPT = 3,5-(2,4,6-i-Pr3C6H2)2C6H3)。通过向THF中的VCl 3(THF)3中添加H 3 [HIPTN 3 N],然后添加LiN(SiMe 3)2,产率为-80%。由[HIPTN3N] V(THF),制备了以下物质:[HIPTN3N] VN2} K,[HIPTN3N] V(NH3),[HIPTN3N] V = NH,[HIPTN3N] V = NSiMe3,[HIPTN3N] V = O,[HIPTN3N] V = S,和[HIPTN3N] V(CO)。在相似的[HIPTN3N] Mo系统中成功使用的条件下,使用[HIPTN3N] VN2} K,[HIPTN3N] V = NH或[HIPTN3N] V(NH3)作为初始物质,
