Ester-directed Ru-catalyzed C-O activation/C-C coupling reaction of ortho-methoxy naphthoates with organoboroneopentylates was written by Zhao, Yigang;Snieckus, Victor. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2016.COA of Formula: C12H17BO3 The following contents are mentioned in the article:
A new, catalytic and general synthetic methodol. for the construction of biaryls and heterobiaryls by the cross-coupling of ortho-methoxy naphthoates with organoboroneopentylates is disclosed. The reaction proceeds under RuH2(CO)(PPh3)3-catalyzed conditions driven by unreactive C-O bond activation of a proximate ester directing group (DG)-catalyst chelation. This one-step synthesis of 2-aryl and -heteroaryl-1-naphthoates has the features of operational simplicity, min. waste and convenient scale-up. The hierarchy of C(O)Me > CONEt2 > CO2Me coordination-assisted reactivity, of potential value in chemoselective synthesis, is also established. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1COA of Formula: C12H17BO3).
2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C12H17BO3
