We report the rhodium-catalyzed base-free decarbonylative borylation of twisted amides. The synthesis of versatile arylboronate esters from aryl twisted amides is achieved via decarbonylative rhodium(I) catalysis and highly selective N-C(O) insertion. The method is notable for a very practical, additive-free Rh(I) catalyst system. The method shows broad functional group tolerance and excellent substrate scope, including site-selective decarbonylative borylation/Heck cross-coupling via divergent N-C/C-Br cleavage and late-stage pharmaceutical borylation. In the experiment, the researchers used many compounds, for example, 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4COA of Formula: C12H16BBrO2).
2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.COA of Formula: C12H16BBrO2
