1,4-Dioxane

Recent Literature


The use of 1,2-bis(dicyclohexylphosphino)ethane (DCyPE) as ligand enabled an iridium-catalyzed transfer hydrogenation of alkenes using 1,4-dioxane as a hydrogen donor. A polystyrene-cross-linking bisphosphine PS-DPPBz produced a reusable heterogeneous catalyst. The reaction tolerates other potentially reducible functional groups such as carbonyl, nitro, cyano, and imino groups.
