Dibutyl Vinylboronate, stabilized with Phenothiazine, is primarily used in organic synthesis as a versatile building block for creating complex molecules. It is particularly valuable in cross-coupling reactions, where it acts as a vinylboron reagent to introduce vinyl groups into target compounds. This chemical is widely employed in the synthesis of pharmaceuticals, agrochemicals, and advanced materials, enabling the formation of carbon-carbon bonds with high precision. Its stabilization with Phenothiazine ensures safer handling and improved shelf life, making it a reliable choice for researchers and industrial chemists. Additionally, it finds applications in polymer chemistry for modifying polymer chains and enhancing material properties.
