Seven derivatives of 1,3-dithiocyclohexane were prepared via the reaction o f 7 aldehydes(or ketones) with Bunte′s salt prepared from 1,3-dichloroprop ane and sodium thiosulfate. The procedure has the feature of easier operation, s horter reaction time and higher yield. The yields of seven derivatives of 1,3- dithiocyclohexane are between 58% and 75%. The optimum molar ratio of 1,3-d ichloropropane to sodium thiosulfate was 1∶1 in the preparati on of Bunte′s salt. The structures of seven derivatives were characterized by m eans of IR, 1H NMR, MS.
