Luo, Feihua published the artcilePalladium-catalyzed ortho-C-H hydroxylation of benzoic acids, Application of 2-Hydroxy-4-(trifluoromethyl)benzoic acid, the publication is Tetrahedron Letters (2021), 153434, database is CAplus.
A simple Pd(OAc)2 catalyzed ortho-hydroxylation of benzoic acids using TBHP as the sole oxidant was explored. This protocol featured relatively broad substrate scope and operational simplicity. The compatibility of ortho-substituted substrates was an effective complement to the previous ortho-hydroxylation reaction.
Tetrahedron Letters published new progress about 328-90-5. 328-90-5 belongs to alcohols-buliding-blocks, auxiliary class Trifluoromethyl,Fluoride,Carboxylic acid,Benzene,Phenol, name is 2-Hydroxy-4-(trifluoromethyl)benzoic acid, and the molecular formula is C8H5F3O3, Application of 2-Hydroxy-4-(trifluoromethyl)benzoic acid.
