Unsaturated 16-electron iridium and rhodium complexes bearing a silyl-bipyridine-based SiNN-pincer ligand (BpySiNN) were synthesized and characterized by x-ray crystallog. and NMR spectroscopy. The iridium-BpySiNN complex facilitated the catalytic C(sp2)-H borylation of arenes to give arylboronate esters in high yields (≥93%) under mild conditions (∼40°). 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 In Synthesis of 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane).
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. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application In Synthesis of 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
