Three substituted salicylaldirnine derivatives H2L1-3 of 2,2'-diamino-6,6'-dimethylbiphenyl give, under appropriate conditions, isolable alkyls of zirconium [ZrL1-3R2] (R = CH2Ph, CH2Bu'). Two molecular structures confirm their cis-alpha geometry (C-2-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 molecular structure of one such doubly-inserted product is presented. The kinetics of decomposition by this process are studied briefly, and it is noted that the rate increases with increased steric demand of the salicylaidimine unit. (C) 2003 Elsevier B.V.
