This chemical is primarily used as a ligand in transition metal catalysis, particularly in cross-coupling reactions such as Suzuki-Miyaura and Heck reactions. Its structure, featuring a phosphine group and an aldehyde moiety, allows it to effectively coordinate with metal centers, enhancing catalytic activity and selectivity. It is also employed in the synthesis of complex organic molecules, including pharmaceuticals and fine chemicals, due to its ability to stabilize reactive intermediates and facilitate desired transformations. Additionally, it finds applications in materials science, where it aids in the development of metal-organic frameworks (MOFs) and other advanced materials with tailored properties.
