SummaryResults are reported on the regioselective C-deuteriation of a series of silyl enol ethers derived from aryl alkyl ketones using deuterium (D 2 ) gas as the deuterium source and palladium-on-barium sulfate as the mediator. These results highlight the numerous reaction pathways and different product types available from simple deuteriation of substituted enol precursors.
SummaryResults are reported on the regioselective C-deuteriation of a series of enol acetates (derived from the aryl alkyl ketones) using molecular deuterium as the D-source and palladium-on-barium sulphate as the mediator. The results presented highlight potential problems associated with the deuteriation of enol acetates.
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.
