摘要
Trialkylaluminum complexes, AIR(3) (R = Me, Et), reacted with the sulfide-bridged his(phenol) tbmpH(2) (tbmpH(2) = 2,2'-thiobis(6-tert-butyl-4-methylphenol)) in a 1:1 ratio to give monoalkyl compounds of the composition "[Al(tbmp)R]" with an unsymmetrical dinuclear structure with both six- and four-coordinate aluminum centers in the solid state. The reaction of 2 equiv of tbmpH(2) gave [Al(tbmp)(tbmpH)], which could be deprotonated with triethylamine to give [NEt3H] [Al(tbmp)(2)]. Upon reaction of [Al(tbmp)R](2) with Lewis bases L (L = Et2O, THF, propylene oxide), monomeric, five-coordinate adducts [Al(tbmp)R(L)] were formed, while 2-propanol gave the dinuclear complex [Al(tbmp)(mu-(OPr)-Pr-i)](2).
