This chemical is primarily used in organic synthesis, particularly in catalytic reactions. It serves as a highly effective catalyst in cross-coupling reactions, such as the Heck, Suzuki-Miyaura, and Negishi reactions, which are widely employed to form carbon-carbon bonds. Its structure, featuring a crotyl group and tri-tert-butylphosphine ligand, enhances its stability and reactivity, making it suitable for complex transformations. It is also utilized in the synthesis of fine chemicals, pharmaceuticals, agrochemicals, and advanced materials, where precise control over reaction pathways is essential.
