A pyridine-promoted diazotization of P-H bonds with aryl diazonium tetrafluoroborates is reported. The method is simple and efficient, providing azo organophosphorus compounds with excellent yields. It avoids the need for complex and harsh reaction conditions and the addition of oxides, and is tolerant to various functional groups. The synthesized azo organophosphorus compounds may find potential applications in organic chemistry and drug design.
