Couplings of benzylic halides mediated by titanocene chloride: synthesis of bibenzyl derivatives

J Org Chem. 2007 Mar 16;72(6):2251-4. doi: 10.1021/jo062492p. Epub 2007 Feb 20.

Abstract

Titanocene monochloride catalyzes the homocoupling of benzylic halides and benzylic gem-dibromides to give the corresponding bibenzyl and stilbenyl systems. Exposure of benzylic bromides to Ti(III) in the presence of aldehydes gave rise to the Barbier-type products. Examples of the utility of the herein described processes are included.
