TL;DR: In this article, a mechanism was proposed for the selective oxidative cyclization of 3-carboxyprqpyl radicals to γ-butyrolactone when using the Na2S2O8-CuSO4 oxidation system.
Abstract: A mechanism was proposed for the selective oxidative cyclization of 3-carboxyprqpyl radicals to γ-butyrolactone when using the Na2S2O8-CuSO4 oxidation system. In this mechanism the Cu(III) ions take part in the reaction.

TL;DR: In this paper, an intramolecular homolytic addition to the CN group was observed for the first time, and the subsequent hydrolysis of the cyclization product, cyanoalkyl radicals of type RĊHXCN, where X is a chain of three carbon atoms and R is hydrogen or alkyl, are converted in aqueous solution into cycloalkanones.
Abstract: Intramolecular homolytic addition to the CN group was observed for the first time. As the result of the reaction, and the subsequent hydrolysis of the cyclization product, cyanoalkyl radicals of type RĊHXCN, where X is a chain of three carbon atoms and R is hydrogen or alkyl, are converted in aqueous solution into cycloalkanones
. The cyanoalkyl radicals, in which X is a chain 4 or 5 C atoms, are partially converted to the corresponding cycloalkanones.
