title: Silver-mediated oxidative C-H/P-H functionalization: an efficient route for the synthesis of benzo[b]phosphole oxides.
abstract: A Ag-mediated C-H/P-H functionalization reaction of arylphosphine oxides with internal alkynes was described for the direct preparation of benzo[b]phosphole oxides with a high yield. An unusual aryl migration on the P-atom derived from a C-P bond cleavage and a new C-P bond formation was also observed and demonstrated to proceed via the radical process.
