NC9H6-8-NHC(But)N-2,6-Pri2-C6H3 (1), was synthesized by the reaction of chloroimine 2,6-Pri2-C6H3-N=C(But)Cl and lithium derivative of 8-aminoquinoline NC9H6-8-NHLi. The elimination of alkane under the action of amidine 1 on Y(CH2SiMe3)2(THF)2 in THF affords bis(alkyl) yttrium complex [NC9H6-8-NC(But)N-2,6-Pri2-C6H3]Y(CH2SiMe3)2(THF) (2), monomeric in the crystalline state.
新的潜在三齿脒在侧链中含有喹啉片段,即 NC9H6-8-NHC(But)N-2,6-Pri2-C6H3 (1),通过氯亚胺 2,6-Pri2- 的反应合成C6H3-N=C(But)Cl 和 8-氨基喹啉 NC9H6-8-NHLi 的锂衍生物。在 THF 中 Y(CH2SiMe3)2(THF)2 上的脒 1 作用下消除烷烃得到双(烷基)钇配合物 [NC9H6-8-NC(But)N-2,6-Pri2-C6H3]Y( CH2SiMe3)2(THF) (2),结晶状态的单体。
