Pentaphenylphosphorus is an organic phosphorane containing five phenyl groups connected to a central phosphorus atom. The phosphorus atom is considered to be in the +5 oxidation state. The chemical formula could be written as P(C₆H₅)₅ or Ph₅P, where Ph represents the phenyl group. It was discovered and reported in 1949 by Georg Wittig.
