Formula: C7H5NO4. Recently I am researching about C-H BONDS; BENZOIC-ACID; MOLECULAR-OXYGEN; N-HYDROXYPHTHALIMIDE; SELECTIVE OXIDATION; METAL-FREE; PHOTOOXIDATION; DERIVATIVES; COBALT; OXIDE, Saw an article supported by the National Key Research and Development Program of China [2017YFC0210900]. Published in GEORG THIEME VERLAG KG in STUTTGART ,Authors: Zheng, K; Yan, XY; Zhang, GF; Yan, XH; Li, XQ; Xu, XS. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
A mild and metal-free procedure is reported for the aerobic oxidation of substituted toluenes to carboxylic acids by using CBr (4) as initiator under irradiation from a 400 nm blue light-emitting diode.
Formula: C7H5NO4. About 4-Nitrobenzoic acid, If you have any questions, you can contact Zheng, K; Yan, XY; Zhang, GF; Yan, XH; Li, XQ; Xu, XS or concate me.
