ChemInform Abstract In a deuterated solvent the photoreduction of title compounds such as (I) leads to β-deuterated main products (cf. (II)). In contrast to the thermal reduction, which affords α-deuterated products, the mechanism of the photoreaction is discussed in erms of sequential electron-hydrogen atom transfer from Hantzsch ester (HAE), an NAD(P)H model, to the substrate in the solvent cage. An electron-proton-electron transfer to the substrate is eliminated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
