So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhou, Xiaocong; Li, Guijie; Shao, Zongzhou; Fang, Kun; Gao, Hongjun; Li, Yuanqiang; She, Yuanbin researched the compound: Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate)( cas:60804-74-2 ).Synthetic Route of C30H24F12N6P2Ru.They published the article 《Four-component acyloxy-trifluoromethylation of arylalkenes mediated by a photoredox catalyst》 about this compound( cas:60804-74-2 ) in Organic & Biomolecular Chemistry. Keywords: trifluoro aryl propyl formate regioselective preparation; aryl alkene Umemoto reagent DMF tandem trifluoromethylation acyloxylation photocatalyst; regioselective trifluoro aryl propyl acetate preparation; Umemoto reagent aryl alkene DMA tandem trifluoromethylation acyloxylation photocatalyst. We’ll tell you more about this compound (cas:60804-74-2).
A four-component intermol. trifluoromethylation-acyloxylation of arylalkenes induced by visible light was developed in the presence of the photoredox catalyst Ru(bpy)3(PF6)2 to afford trifluoro-(aryl)propyl formates/acetates I [R1 = 4-Me, 2,5-Me2, 3-Cl, etc.; R2 = H, Me] under mild reaction conditions. A new Umemoto’s reagent was used as a trifluoromethyl radical source, and this redox neutral reaction demonstrated good functional group tolerance for aryl alkenes with high yields up to 91%. The detailed reaction process was investigated based on control, deuterium and O18-labeling experiments to support that N,N-dimethylformamide (DMF)/H2O acted as an acyloxyl source.
