General Description

2,6-Bis(diphenylphosphino)pyridine, also known as P,P'-bis(diphenylphosphino)pyridine or dppp, is a bidentate ligand commonly used in coordination chemistry and organometallic catalysis. 2,6-BIS(DIPHENYLPHOSPHINO)PYRIDINE consists of a pyridine ring with two diphenylphosphine groups attached at the 2 and 6 positions, making it a chelating ligand that can form stable complexes with various transition metals. Due to its strong coordinating ability and steric bulk, 2,6-bis(diphenylphosphino)pyridine is often utilized in homogeneous catalysis for a variety of organic transformations, such as hydrogenation, cross-coupling reactions, and polymerization processes. Its use in catalytic reactions has contributed to the development of more efficient and selective synthetic methodologies in the field of chemical synthesis.
