文摘
The synthesis and structure of neutral and cationic aluminum compounds equipped withthe intramolecular donating C(SiMe3)2SiMe2(2-C5H4N) ligand denoted by Pytsi is described.The compounds (Pytsi)AlMe2 (1), (Pytsi)AlEt2 (2), [(Pytsi)AlMe]+[MeB(C6F5)3]- (3), and[(Pytsi)AlMe(thf)]+[MeB(C6F5)3]- (3·thf) have been synthesized and characterized by standardmethods, and the molecular structures of 1, 2, and 3 have been determined by single-crystalX-ray analyses. Compound 3 was obtained by an addition of 1 equiv of B(C6F5)3 to thedimethyl species 1. The salt-like title compound 3 shows a methyl group in a bridging positionbetween Al and B atoms consisting of a long Al-C distance of 2.380(2) Å and a B-C bondlength of 1.681(3) Å.
