2,4,4,6-Tetraaryl-4H-thiopyrans Ia-Ig react smoothly with carbon disulfide solution of chlorine already at 0 deg C yielding the corresponding 3,5-dichloro derivatives IIa-IIg.With longer reaction time and temperature raised to 20 deg C, the 4H-thiopyrans

The reaction of dibromine with the heterocycles I-IV gives corresponding 3,5-dibromo derivatives, while the less selective reactions with dichlorine afforded 3,5-dichloro derivative XII only in the case of 4H-thiopyran IV and trichloro derivative of the p
