2,2'-Biphenylene phosphorochloridite

2,2′-Biphenylene phosphorochloridite is the name for a polycyclic organophosphorus compound with the formula C12H8O2PCl. It is a precursor to diphosphite ligands such as BiPhePhos by reaction with suitable diols. 2,2′-Biphenylene phosphorochloridites, which is a white solid, is prepared from 2,2′-biphenol and phosphorus trichloride. It is prepared by the reaction of 2,2′-biphenol and phosphorus trichloride.[1][2]
