A convenient PNP pincer manganese catalyzed transfer hydrogenation of bromides to corresponding debrominated aryl compounds using ethanol as the hydrogen sources is reported. Importantly, the application of biomass-derived ethanol highlights the sustainability of the methodology. The use of 6phenyl substituted triazine-based P ipr N 5 P ipr manganese pincer catalyst allows for the debromination of various aryl bromides with good yields. Notably, the process also occurs with bromides derived from several classes of natural products and bioactive compounds, such as citronellol, diacetone fructose, cholesterol, and vitamin E.
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.
