A flask was charged with 2.0 g (4.8 mmol) of diphenyliodonium triflate, 0.93 g (5.0 mmol) diphenyl sulfide and 37 mg of copper benzoate. The mixture was heated under argon for 3 h (bath 125° C.). After cooling, the mixture was triturated with hot ether and stirred 1 h. The solid was filtered and recrystallized from 1:1 butyl acetate-isopropanol (1.6 g, 80%, mp 134°-6° C.).
