资源简介：
Reactions of N-aryliminopyrrolyl ligand 1a, 2-(2,6-iPr2C6H3NCH)-C4H3NH (ImpDipp-H), with dibenzylcalcium gave two types of pyrrolylcalcium
complexes, bis(iminopyrrolyl)calcium (2a) and (amidopyrrolyl)calcium
(3a), via alkane elimination and ligand alkylation reaction,
respectively. Preparation of a mono(iminopyrrolyl) complex, (iminopyrrolyl)Ca[N(SiMe3)2](THF)2 (4a), was accomplished
by the addition of 1 equiv of 1a to Ca[N(SiMe3)2]2(THF)2. A series of group 2
metal bis(iminopyrrolyl) complexes, [(ImpDipp)2M(THF)3] (M = Sr (5a), Ba, (6a)) and [(ImpMe)2Ca(THF)2] (2b) (2-(4-MeC6H4NCCH3)-C4H3NH (ImpMe-H)), was selectively
prepared via amine elimination reactions, and their molecular structures
were clarified by X-ray diffraction studies.
