Kirihara, Masayuki published the artcileAerobic Photooxidation of Toluene Derivatives into Carboxylic Acids with Bromine-Water under Catalyst-Free Conditions, Formula: C9H8O4, the publication is Synlett, database is CAplus.
The photoirradiation of toluene derivatives with two equivalent of bromine in benzotrifluoride-water provided a satisfactory yield of the corresponding benzoic acid derivatives Either a fluorescent lamp, blue LED (454 nm), or UV LED (385 nm) was used for the photoreaction. The reaction pathway might proceed through the dibromination of benzylic carbon, generation of the benzylic radical via oxidative C-H abstraction, formation of benzoyl bromide, and hydrolysis of carboxylic acid.
Synlett published new progress about 1877-71-0. 1877-71-0 belongs to esters-buliding-blocks, auxiliary class Carboxylic acid,Benzene,Ester, name is 3-(Methoxycarbonyl)benzoic acid, and the molecular formula is C9H8O4, Formula: C9H8O4.
