Enantioselective iodocycloetherifications can be conducted using sterically highly demanding BINOL-based phosphoric acid diesters as catalyst. To achieve enantioselective reactions, cocatalysis by triphenylphosphine selenide is necessary. With cocatalysis, good to excellent enantioselectivities achieved for a broad range of substrates catalyst and cocatalyst loadings low 1 mol %. The itself doe...
A deprotection-free method was developed for the synthesis of graphdiyne (GDY) powder with in-situ formed CuO nanoparticles, as reported by Mohamed Nawfal Ghazzal, Li-Zhu Wu et al. in their Research Article (e202210242). The prepared CuO/GDY demonstrated to be an excellent co-catalyst photocatalytic hydrogen evolution, comparable state-of-art Pt cocatalyst. work will widen use GDY and facilitat...
We report the development of a highly efficient photocatalytic system by immobilizing high-quality CdS quantum dots and dendritic Pt nanocrystals on thiol-functionalized graphene substrates. We have demonstrated that the use of QDs with compact sizes leads to a dramatically enhanced performance in comparison with their bulk counterparts. Our design allows for systematic examination of the impac...
