The first project: In this research work, the polystyrene-cross-linking bisphosphine ligand PS-DPPBz was effective for the Ir-catalyzedreversible acceptorless dehydrogenation/hydrogenation of N-heterocycles. Notably, this protocol is applicable to the dehydrogenation of N-substituted indoline derivatives with various N-substituents with different electronic and steric natures. A reaction pathway involving oxidative addition of an N-adjacent C(sp3)-H bond to a bisphosphine-coordinated Ir(I) center is proposed for the dehydrogenation of N-substituted substrates. The second project: Design new material for hydrogen storage carriers.
