The direct addition of P(O)–H bonds (dialkylphosphites and diphenyl phosphonite) across various activated alkenes was catalyzed effectively by 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD). This is a mild, rapid and efficient protocol to generate P–C bonds. This simple procedure allows a series of dialkylalkylphosphonates and trisubstituted phosphine oxides to be prepared in high yields. Further investigation
