Abstract
A pyridine-promoted diazotization of PH bonds with aryl diazonium tetrafluoroborates is established. The reported method is simple and efficient for the synthesis of azo organophosphorus compounds with excellent yields, which avoids the adoption of complex and harsh reaction conditions and the addition of oxides, tolerating various kinds of functional groups. The synthesized azo organophosphorus compounds may have potential applications in organic chemistry and drug design.
