Abstract

The reduction of diimine ArMid-bian (L) (ArMid-bian = (1-[2,6-dibenzhydryl-4-methylphenyl]-2-[2,6-di-isopropylphenyl]iminoacenaphthene) with excess magnesium, calcium, strontium, or barium in the presence of catalytic amounts of the corresponding iodides results in the formation of complexes [(ArMid-bian)Mg(Thf)(Dme)] (I), [(ArMid-bian)Ca(Dme)2] (II), [(ArMid-bian)Sr(Dme)2] (III), and [(ArMid-bian)Ba(Dme)2] (IV) containing the ArMid-bian dianion. Compounds L, I−IV were characterized by IR and NMR spectroscopy, elemental analysis, and X-ray diffraction (CCDC no. 2 440 721 (L), 2 440 722 (I), 2 440 723 (II), 2 440 724 (III), 2 440 725 (IV)).
