, p. 5240 - 5245 (2020/07/03)
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.

Paragraph 0072-0074, (2017/09/19)
PROBLEM TO BE SOLVED: To provide a hydrogen acceptor capable of storing and releasing hydrogen, and a hydrogen donor conjugate therewith. SOLUTION: The invention provides pyrroloindole derivatives represented by general formula (1) (where R1 represents a C1-4 alkyl group, and R2 represents a hydrogen atom or C1-4 alkyl group; and a double line of a broken line and a solid line represents a single bond or double bond). Also provided are methods of producing them. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT
