Wen, Si published the artcileRuthenium(
A ruthenium(II)-catalyzed C-H activation/annulation reaction of benzoic acids and CF3-imidoyl sulfoxonium ylides enabled by weak O-coordination was achieved. A series of 3-trifluoromethyl-isoquinolinones I [R = Ph, 2-MeC6H4, CH2CH2Ph, etc.; R1 = 8-Me, 7-F, 6-I, etc.; R2 = F, CF2CF3, CF2CF2CF3] were synthesized in 37-75% yields under redox-neutral reaction conditions.
Organic Chemistry Frontiers published new progress about 118-90-1. 118-90-1 belongs to catalysis-chemistry, auxiliary class Carboxylic acid,Benzene,Natural product, name is 2-Methylbenzoic acid, and the molecular formula is C4H6BrFO2, Safety of 2-Methylbenzoic acid.
