3-Furanboronic acid is a type of 3-呋喃硼酸, where furan acts as a π-excessive heteroaromatic compound. In chemical synthesis, it demonstrates good reactivity with various 2-苯并呋喃硼酸. It can react successfully with 3-溴噻吩, 2,3-溴吡啶, or 3-溴喹啉 using only a small amount of catalyst. Coordination between heteroatoms and the palladium center prevents any poisoning effect from being observed.
