Cas no 1256781-64-2 (2-(2,5-Dibromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane)

2-(2,5-Dibromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is a brominated phenylboronic ester commonly employed as an intermediate in Suzuki-Miyaura cross-coupling reactions. Its dibromo substitution pattern enhances reactivity in selective aryl-aryl bond formations, while the dioxaborolane moiety ensures stability and handling convenience. The tetramethyl substitution on the borolane ring improves solubility in organic solvents, facilitating its use in homogeneous reaction conditions. This compound is particularly valuable in pharmaceutical and materials science research, where precise functionalization of aromatic systems is required. Its well-defined structure and reliable performance make it a preferred choice for constructing complex polycyclic frameworks. Storage under inert conditions is recommended to maintain purity and reactivity.
