Cas no 195730-31-5 (Bicyclo[4.2.0]octa-1,3,5,7-tetraen-3-ylboronic acid)

Bicyclo[4.2.0]octa-1,3,5,7-tetraen-3-ylboronic acid is a specialized boronic acid derivative featuring a strained bicyclic framework with conjugated double bonds. This structure imparts unique reactivity, making it a valuable intermediate in Suzuki-Miyaura cross-coupling reactions for constructing complex polycyclic systems. The rigid bicyclic core enhances steric control in coupling processes, while the boronic acid group ensures compatibility with diverse aryl and vinyl halides. Its conjugated system may also facilitate applications in materials science, particularly in the synthesis of π-conjugated polymers or small-molecule semiconductors. The compound’s stability under anhydrous conditions and well-defined reactivity profile make it suitable for precision synthetic applications.
