A chemoselective rhodium-catalyzed borylation has been developed for the preparation of aryl boronate esters. The reaction proceeds under mild conditions with excellent selectivity for C-I bonds in bromoiodoarenes and exhibits broad functional group tolerance. This procedure can act as a complementary approach toward bifunctional arenes along with other metal-catalyzed borylations. Addnl., the reaction’s utility in the preparation of monomers for metal-catalyzed cross-coupling polymerization is demonstrated. In the experiment, the researchers used many compounds, for example, 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4Application of 68716-49-4).
2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application of 68716-49-4
