The regiochemistry of the coupling between p-nitrobenzylic radicals and aci-nitronate ions in the association step of SRN1 reactions is shown to be dependent on steric factors.Branching at the carbon which is α to the reaction site causes a shi

The rate and regiochemistry of the SRN1 reactions of aci-nitronates with p-nitrobenzylic substrates are profoundly affected by branching at the positions adjacent to the reaction sites (Cβ).Definitive rules which predict whether C-alkylation will occur in the association step involving p-nitrobenzylic radicals and aci-nitronate ions are formulated. β-Branching causes O-alkylation or reductive processes to increase.In some cases no recognizable product formation results.Benzylic alcohols, p-nitrophenyl alkyl ketones and/or their oximes, and p-nitrophenol are among the products which result from subsequent reactions of the O-alkylation products, aci-nitronic esters of benzylic alcohols.
