Mechanistic investigation on the reaction of 1,1-di-p-substituted phenyl-2,2-dinitroethylene with 1-benzyl-1,4-dihydronicotin-amide in oxygen saturated acetonitrile—clear evidence for intermediate mechanism
The reaction of 1-benzyl-1,4-dihydronicotinamide with a series of 1,1-di-p-substituted-phenyl-2,2-dinitroethylenes in oxygen-saturated acetonitrile produced various amounts of the corresponding ethanes and diaryl ketones according to the electronic structure of the substituent groups indicating a spectrum of intermediate mechanism between polar mechanism and SET mechanism.
