16.4 g (0.05 mol) of 3-phenyl-3-(trichlorogermyl)propionic acid was dissolved in 200 ml of anhydrous acetone. 12.6 g (0.16 mol) of anhydrous pyridine was added to the solution under cooling with an ice bath, followed by stirring. Dry hydrogen sulfide was introduced into the mixture for one hour. The acetone was removed and the residue was dissolved in 50 ml of ethanol. The solution was added to 400 ml of water to precipitate the crystal. The crystal was recrystallized from a mixture of methyl acetate and benzene (1:3) to obtain 12.7 g of crystalline sesquisulfide of 3-phenyl-3-germylpropionic acid. ##STR14## sesquisulfide of 3-phenyl-3-germylpropionic acid (18).
