摘要：
Reaction of [{(R)-C20H12O2}Ti((OPr)-Pr-i)(2)] with 1,4-dithiaalkanediyl-2,2'-bis(6- tert-butyl-4-methyl-phenol) affords the chiral-at-metal complex [{(R)-C20H12O2} Ti{(C6H2O-'Bu-6-Me-4)(2)S(CH2)(2)S}] (1) in low diastereomeric excess. Complex I can be partially hydrolyzed to give a dinuclear species [mu-{(R)-C20H12O2}-mu-O-{(Lambda)-Ti[(C6H2O-Bu-t-6-Me-4)(2)S(CH2)(2)S]}(2)] (2), in which the two titanium centers are homochiral. The molecular structure of 1 and 2 was confirmed by single crystal X-ray analysis, which shows C-2-symmetry in both complexes. (c) 2006 Elsevier B.V. All rights reserved.
