Multinuclear alkylene zinc (MAZ) compounds of the type EtZn-(R ″-Zn) n-Et (R ″= ethyl and propyl branched alkylene groups) were synthesized by a simple one-step procedure in nonpolar hydrocarbon solvents from α, ω-dienes (eg, 1, 7-octadiene or 1, 9-decadiene) and diethylzinc using a bis (salicylaldiminato) Zr (IV) complex,[(2-methylcyclohexyl) N CH (2-O- C6H3-3, 5-di-tert-butyl)] 2ZrMe2, as a catalyst. The MAZ serves as a divalent reversible ...
