초록

Stereochemical course of the reductive decyanation of two stereoisomeric 4-t-butyl-1-phenylcyclohexanecarbonitriles 3 and 4 using solvated electron has been studied. While sodium-mediated reactions of both 3 and 4 in the presence of alcohols give the same ratio, 1.5 : 1, in favor of the thermodynamically more stable product 5 over the other one 6, the ratios obtained from the potassium-mediated process are found to be very sensitive to the kind of H-donors. When reactions are performed without H-donors, 5 is only obtained from the experiments with both stereoisomers irrespective of the metal species.
