Wu, Jianglong published the artcileCu(II)-Catalyzed Ligand-Free Oxidation of Diarylmethanes and Second Alcohols in Water, Safety of Bis(4-fluorophenyl)methane, the publication is Chinese Journal of Chemistry (2017), 35(9), 1391-1395, database is CAplus.
A simple and efficient Cu(II)-catalyzed ligand-free oxidation of diarylmethanes, e.g., 9H-xanthene and secondary alcs., e.g., 2,3-dihydro-1H-Inden-1-ol using 70% tert-Bu hydroperoxide (TBHP) in water were developed. A series of diarylmethanes were directly oxidized into diaryl ketones, e.g., 9H-xanthen-9-one in 67%-98% yields. Addnl., various secondary alcs. were also transformed into the desired products in 48%-98% yields. Importantly, the catalytic system in the absence of any organic solvent, surfactant, or phase transfer agent, had a wide substrate scope and a high tolerance for various functional groups.
Chinese Journal of Chemistry 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 C25H47NO8, Safety of Bis(4-fluorophenyl)methane.
