Ma, Hongpeng; Bai, Chaolumen; Bao, Yong-Sheng published an article in 2019, the title of the article was Heterogeneous Suzuki-Miyaura coupling of heteroaryl ester via chemoselective C(acyl)-O bond activation.COA of Formula: C7H4ClNO4 And the article contains the following content:
A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters RC(O)OR1 (R = naphthalen-1-yl, furan-2-yl, 1H-indol-2-yl, etc.; R1 = pyridin-2-yl, pyrazin-2-yl, 4-methylquinolin-2-yl, etc.) and arylboronic acids R2B(OH)2 (R2 = Ph, 2H-1,3-benzodioxol-5-yl, 4-phenoxyphenyl, etc.) as coupling partners was developed. This methodol. provides a heterogeneous catalytic route for aryl ketones RC(O)R2 formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS anal. of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd0/PdII catalytic cycle that began with Pd0. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).COA of Formula: C7H4ClNO4
