Though the reaction of chalcones 2 with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide 1 in refluxing benzene gave the corresponding thiochalcone dimers 3, the reaction in refluxing xylene gave new phosphorus-containing compounds, 2-(4-methoxyphenyl)-3,5-diaryl-Δ⁴-1,2-thiaphospholene-2-sulfides 4.
