In 2022,Nandi, Shantanu; Mondal, Shuvam; Jana, Ranjan published an article in iScience. The title of the article was 《Chemo- and regioselective benzylic C(sp3)-H oxidation bridging the gap between hetero- and homogeneous copper catalysis》.Electric Literature of C7H5IO2 The author mentioned the following in the article:
An expedient synthesis of privileged seven-membered lactones, dibenzo[c,e]oxepin-5(7H)-one through a highly chemoselective benzylic C(sp3)-H activation was disclosed. Remarkably, the formation of widely explored six-membered lactone via C(sp2)-H activation was suppressed under the present conditions. The reaction proceeded smoothly on use of inexpensive metallic copper catalyst and di-tert-Bu peroxide (DTBP). Owing to the hazards of stoichiometric DTBP, further, a sustainable metallic copper/rose bengal dual catalytic system coupled with mol. oxygen replacing DTBP was developed. A 1,5-aryl migration through Smiles rearrangement was realized from the corresponding diaryl ether substrates instead of expected eight-membered lactones. The present methodol. was scalable, applied to the total synthesis of cytotoxic and neuroprotective natural product alterlactone. The catalyst was recyclable and the reaction could be performed in a copper bottle without any added catalyst. The experimental process involved the reaction of 2-Iodobenzoic acid(cas: 88-67-5Electric Literature of C7H5IO2)
2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Electric Literature of C7H5IO2
