We investigated the reductive elimination of several functionalized and non-functionalized vic-dibromides with 1,2-diphenyl-, 1, 1,2,2-tetraphenyl- and l-phenyl-2-(2-pyridyl)-1,2-disodioethane. The reaction, involving some of the less expensive organic and inorganic reagents, proceeds under mild conditions, and is tolerant of a variety of functional groups. Extension of this procedure to similar 1,2-disubstituted compounds was also investigated. Reductive eliminations run on stereochernical probe compounds strongly suggest that this reaction proceeds via a "single electron" reductive elimination reaction pathway. (c) 2007 Elsevier B.V.
