WebNov 22, 2024 · General procedure for the preparation of β -hydroxy-phosphine oxides 3 To a stirring solution of alkene (1.0 mmol) and diphenylphosphine oxide (2.0 mmol) in MeOH (5 mL) at 30 °C was added Mn (OAc) 3 (2.0 mmol) in portions over 30 min. Both phosphine oxides and phosphonates are suitable precursors for the delivery of phosphinoyl radicals. As a result, phosphinoyl radicals along with another functional group such as heteroaryl, cyano, or imino are incorporated to alkenes concurrently. A wide range of synthetically valuable alkylphosphorus compounds are furnished in good yields.
