β¦ Synopsis
In order to gain some insight into the mechanism of metallation.and of homogeneous and heterogeneous dissolving metal reductions, we have undertaken a study involving the reduction of optically active (+)-(S-)-l-.bromo-1-methyl-2,2-diphenylcyclopropane. This system is ideally suited for such an investigation since the optical purities and tht absolute configurations of both the starting material and the product, l-methyl-2,24iphenylcyclopropane, are known'. Moreover, in contrast to most
