This chemical is primarily used in organic synthesis as an intermediate for the preparation of various complex molecules. It is particularly valuable in the construction of carbon-carbon bonds through reactions like the Heck coupling, where it facilitates the formation of alkenes. Additionally, it serves as a key reagent in the synthesis of biologically active compounds, including pharmaceuticals and agrochemicals. Its tosyloxy group makes it a versatile building block for introducing functional groups into organic frameworks, enabling the development of novel materials and fine chemicals.
