Cas no 1119899-36-3 ((4-Cyanobenzo[b]thiophen-2-yl)boronic acid)

(4-Cyanobenzo[b]thiophen-2-yl)boronic acid is a boronic acid derivative featuring a benzo[b]thiophene core substituted with a cyano group at the 4-position and a boronic acid moiety at the 2-position. This compound serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex heterocyclic architectures. The electron-withdrawing cyano group enhances reactivity in palladium-catalyzed transformations, while the boronic acid functionality ensures compatibility with diverse aryl and heteroaryl halides. Its stability under mild conditions and high purity make it suitable for pharmaceutical and materials science applications, particularly in constructing conjugated systems for optoelectronic materials or bioactive molecules. Proper handling under inert atmosphere is recommended to preserve reactivity.
