[(Me3AlCTp3‐Me)Mg(AlMe4)], respectively, with monoanionic tripodal ligands. Treatment of sterically less demanding RCTp3‐R′ with Mg(AlMe4)2 produced isostructural dicationic “metal‐in‐a‐box” complexes of the type [(RCTp3‐R′)2Mg][AlMe4]2 (R=Me, nBu; R′=H, Me). Utilization of the superbulky ligands MeCTp3‐Ph and MeCTp3‐tBu gave monocationic complexes [(MeCTp3‐Ph)MgMe][AlMe4] and [(MeCTp3‐tBu)MgMe][Al2Me7] as
合成了一系列RCTp 3-R'(R = Me,n Bu,SiMe 3 ; R'= H,Me,Ph,i Pr,t Bu)类型的三(吡唑基)烷烃(RCTp)蝎形配体,并他们协调甲基镁部分的能力进行了审查。Mg(AlMe 4)2与中性配体HCTp 3-Ph或Me 3 SiCTp 3-Me的反应,其中包含非纯主链次甲基部分,导致去质子/重排,SiMe 3 / AlMe 3交换得到[[Me 3 AlCTp 3-Ph)2 Mg]和[(Me 3AlCTp 3-Me)Mg(AlMe 4)],分别带有单阴离子三脚架配体。的空间要求不高RCTP治疗'3-R用Mg(阿尔梅4)2生产的类型[(RCTP的同构的双阳离子“金属在一箱”复合物3-R' )2的Mg] [阿尔梅4 ] 2( R = Me,n Bu; R′= H,Me)。所述配体superbulky MeCTp利用3-PH和MeCTp 3-吨卜,得到单阳离子配合物[(MeCTp
