  DOI：10.1055/s-1995-3878

  日期：1995.2

  Palladium(0)-triphenylphosphine complex-catalyzed debrominative coupling reaction of (tribromomethyl)benzenes gave diarylacetylenes or a mixture of (E)- and (Z)-α,β-dibromostilbenes depending upon the substrate and the solvent being used. On the other hand, (dibromomethyl)benzenes afforded (E)-stilbenes selectively under the same reaction conditions.

  Three electrons from Sm(0) to Sm(III) can be available during the title reduction which was achieved in 90–95% yield with vic-dibromides such as trans-10,11-dibromodibenzosuberone, meso- and dl-1,2-dibromo-1,2-diphenylethane, ethyl 2,3-dibromo-3-phenylpropionate, 2,3-dibromo-3-phenylpropionic acid, and cholesterol dibromide. These reductions were accelerated with a catalytic amount of acid.
