Six new hindered alpha,beta -unsaturated ketones (22c-h) were prepared. Though the reaction of alpha,beta -unsaturated ketones (22a,b) with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (23) in refluxing benzene gave the corresponding 2-arylidene-1-thiotetralone dimers (26a,b) and 3H-1,2-thiaphospholene-2-sulfides (28a,b), the reaction of hindered alpha,beta -unsaturated ketones (22d-h) with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (23) in refluxing benzene gave only identified 3H-1,Zthiaphospholene-2-sulfides (28c-g).
