Develop New Reactions based on Heterocyclic C(sp3)–H Bond Activation

Research Project

Project/Area Number	18J20833
Research Institution	Hokkaido University
Principal Investigator	ZHANG DELIANG 北海道大学, 大学院総合化学院, 特別研究員(DC1)
Project Period (FY)	2018-04-25 – 2021-03-31
Keywords	heterogeneous catalyst / dehydrogenation / heterocycles
Outline of Annual Research Achievements	The first project: In this research work, the polystyrene-cross-linking bisphosphine ligand PS-DPPBz was effective for the Ir-catalyzed reversible 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.
