    • Typical Experimental Procedure: To a solution of diphenyl ditelluride (0.6 mmol) in anhyd MeOH (2 mL) was added dropwise a solution of Br2 (0.60 mmol) and MeOH (1.2 mL) under nitrogen atmosphere. The mixture was stirred at r.t. for 2 h. Then 1,2-allenic phosphonates 1 (1.0 mmol) in anhyd MeOH (2 mL) was added to the above PhTeBr solution with stirring, and the reaction mixture was heated to 55°C After the reaction was complete (2 h, the mixture was concentrated and the residue was purified by flash chromatography to afford 4-(phenyltelluro)-1,2-oxaphosphol-3-ene 2-oxides 2.
