Riley, Robert D.; Huchenski, Blake S. N.; Bamford, Karlee L.; Speed, Alexander W. H. published the artcile< Diazaphospholene-Catalyzed Radical Reactions from Aryl Halides>, Reference of 81107-97-3, the main research area is heterocyclic compound preparation photochem; aryl halide radical cyclization diazaphospholene catalyst; Catalysis; Diazaphospholene; Heterocycles; Photochemistry; Radical Addition.
Herein, stoichiometric radical cyclizations of aryl iodides such as 1-iodo-2-[(3-phenylprop-2-en-1-yl)oxy]benzene and 1-iodo-2-[(3-methylbut-2-en-1-yl)oxy]benzene mediated by diazaphospholene hydrides are made catalytic by the combination of phenylsilane and alkali metal salts to regenerate the diazaphospholene hydride. The scope was expanded to include aryl bromides 2-Br-3-R-4-R1-5-R2C6HXR3 (X = O, S; R = H; R1 = H, F, CN, CF3, C(O)OMe; RR1 = -CH=CH-CH=CH-; R2 = H, CF3; R3 = 3-phenylbut-2-en-1-yl, 3-methylbut-2-en-1-yl, 3-phenylprop-2-en-1-yl, etc.), which benefit from visible light irradiation Twenty one substrates underwent cyclization, including a dearomative cyclization. Extension to six intermol. radical hydroarylations with arenes, thiophenes, and a pyridine e.g., 2-iodobenzotrifluoride was also accomplished.
Angewandte Chemie, International Edition published new progress about Aryl halides Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 81107-97-3 belongs to class bromides-buliding-blocks, and the molecular formula is C7H4BrF3O, Reference of 81107-97-3.
