文摘

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