In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Photoredox/cobaloxime co-catalyzed allylation of amines and sulfonyl hydrazides with olefins to access α-allylic amines and allylic sulfones, published in 2021, which mentions a compound: 60804-74-2, Name is Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), Molecular C30H24F12N6P2Ru, Application of 60804-74-2.
A dual-catalytic platform for the allylation of N-phenyltetrahydroisoquinolines I (R = R1 = H, OMe; R2 = H, 3-Me, 2-OMe, 4-Cl) and sulfonyl hydrazides R3SO2NHNH2 (R3 = Ph, cyclopropyl, Pr, etc.) with olefins CH3C(=CH2)R4 (R4 = C(O)OMe, C(O)OCH(CH3)2, C6H5, 4-ClC6H4, etc.) to selectively access α-allylic amines II and allylic sulfones R3SO2CH2C(=CH2)R4 in good yields by combining photoredox catalysis and cobaloxime catalysis was reported. This strategy avoided the use of a stoichiometric amount of terminal oxidant and the use of pre-functionalized allylic precursors, representing a green and ideal atom- & step-economical process. Good substrate scope and gram-scale synthesis demonstrated the utility of this protocol. Mechanistic studies revealed that a radical process is probably involved in this reaction.
