characterized by an X-raycrystalstructure analysis. Treatment of this mixture with Zr(NMe2)4 led to in situ deprotonation and formation of complex [(C5H4)-CH═NAr]2Zr(NMe2)2 (6) in a mixture with the exchange product [(C5H4)-CH═NAr]2Zr(NMe2)(NH-Ar) (7) as a minor component (both characterized by X-ray diffraction). The corresponding reaction with the reagent Zr(benzyl)4 or Cl2Zr(NMe2)2(THF)2 resulted in the
6- dimethylaminofulvene的治疗1与锂代-2,6- diisopropylanilide 2,得到锂化的6-(2,6-二异丙基苯胺基)富烯3。用Me 3 SiCl处理得到N-甲硅烷基化衍生物(C 5 H 4)═CH-N(Ar)SiMe 3(4),其特征在于X射线衍射。通过用乙酰丙酮处理产生3的质子化,以产生被一些2,6-二异丙基苯胺污染的合成的顺式和反式5 [(C 5 H 4)= CH-N(Ar)H]的混合物。次要异构体syn- 5还通过X射线晶体结构分析表征。用Zr(NMe 2)4处理该混合物可导致原位去质子化,并与交换产物[ [C 5 H 4 ] -CH 3 NAr] 2 Zr(NMe 2)2(6)形成复合物。(C 5 H 4)-CH 3 NAr] 2 Zr(NMe 2)(NH-Ar)(7)作为次要成分(均以X射线衍射为特征)。与试剂Zr(苄基)4或Cl 2 Zr(NMe
