Li, Jiang-Sheng published the artcilet-BuONa-Mediated Transition-Metal-Free Autoxidation of Diarylmethanes to Ketones, Safety of Bis(4-fluorophenyl)methane, the publication is Synlett (2017), 28(8), 994-998, database is CAplus.
Autoxidative sp3 C-H transformation of diarylmethanes ArCH2Ar1 (Ar = Ph, 2-chlorophenyl, 3,4-dimethylphenyl, etc.; Ar1 = 2-methoxyphenyl, 4-nitrophenyl, 3,4-dichlorophenyl, etc.) has been demonstrated using O2-mediation by t-BuONa. This protocol enables an alternative route for the access to diaryl ketones ArC(O)2Ar1 from benzyl derivatives in good to excellent yields under mild reaction conditions, without transition metal catalysts or addnl. chem. oxidants.
Synlett published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C13H10F2, Safety of Bis(4-fluorophenyl)methane.
