Abstract
Reductive dehalogenation of 2,4-dichloro-2,4-dicyano-pentane using zinc together with viologens as an electron transfer catalyst under mildconditions produced cis- and trans-1,2-dicyano-1,2-dimethylcyclopropane (cis:trans = 84:16) in 91% yield. The reactions of 1,3-dibromo-1,3-diphenylpropane and 1,3-dichloro-1,3-diphenylpropane under the same conditions produced the 1,2-diphenylcyclopropane in a good yield. The reaction was assumed to proceed via two electrons transfer from zinc to the dihalides and subsequent dehalogenation.
