Abstract

Three substituted salicylaldimine derivatives H2L1–3 of 2, 2′-diamino-6, 6′- dimethylbiphenyl give, under appropriate conditions, isolable alkyls of zirconium [ZrL1– 3R2](R= CH2Ph, CH2But). Two molecular structures confirm their cis-α geometry (C2- symmetric with cis alkyl ligands). They decompose via 1, 2-migratory insertion of an alkyl group to imine, followed in some instances by a second similar reaction. The dimeric ...
