Sodium 4-(2-dicyclohexylphosphanylphenyl)-3,5-di(propan-2-yl)benzenesulfonate hydrate (CAS: 870245-84-4) is a complex organophosphorus compound that has garnered significant attention in the field of organic chemistry, particularly as a sophisticated phosphine ligand. Its molecular structure is key to its functionality, offering a unique combination of steric bulk and electronic characteristics that can profoundly influence catalytic processes.

The molecule features a biphenyl core substituted with isopropyl groups and a phosphine moiety. The phosphine atom is further bonded to two bulky cyclohexyl rings, contributing significant steric hindrance. This steric bulk is crucial in catalysis as it can dictate the coordination geometry around a metal center, favoring specific reaction pathways and suppressing undesired side reactions. Attached to the biphenyl system is a benzenesulfonate group, which is deprotonated and counterbalanced by a sodium ion. This ionic sulfonate group renders the molecule water-soluble, a highly desirable trait for green chemistry applications and reactions conducted in aqueous or biphasic media. The presence of hydration indicates that water molecules are associated with the salt in its crystalline form.
