Zhang, Yajun; Jiang, Dandan; Fang, Zheng; Zhu, Ning; Sun, Naixian; He, Wei; Liu, Chengkou; Zhao, Lili; Guo, Kai published the artcile< Photomediated core modification of organic photoredox catalysts in radical addition: mechanism and applications>, Application of C8H8BrF, the main research area is bismethoxyphenyl dihydrophenazine bromoalkane photochem cross coupling; alkyl bisphenyl dihydrophenazine preparation.
Here, a new kind of core modification for dihydrophenazines, phenoxazines and phenothiazines was developed through this cross-coupling process. Mechanistic studies suggested that the radical species would be more likely to couple with OPC’ radical cations rather than the ground-state OPC. Core modification of OPCs could stabilize the radical ions in an oxidative quenching catalytic cycle. Significantly, core modifications of OPCs could lower the energy of light required for photoexcitation. Compared with their noncore-modified counterparts, all the core-modified dihydrophenazines and phenoxazines exhibited efficient performance in controlling O-ATRP for the synthesis of poly(Me methacrylate) with higher initiator efficiencies under the irradiation of simulated sunlight.
