1, 5-Dichloro-9H-thioxanthen-9-one (2) was prepared by cyclization of 2-chloro-6-[(2-chlorophenyl)thio]-benzoic acid (10) obtained from 2-chloro-6-iodobenzoic acid (9) and 2-chlorobenzenethiol. Similarly, 1, 7-di-chloro-9H-thioxanthen-9-one (6) was prepared from 9 via 2-chloro-6-[(4-chlorophenyl)thio]benzoic acid (11). Compound 6 was also obtained by condensation of 2-chloro-6-mercaptobenzoic acid
通过将由2-氯-6-得到的2-氯-6-[(2-氯苯基)硫代]-苯甲酸(10)环化,制得1,5-二氯-9 H-噻吨-9-一(2)。碘苯甲酸(9)和2-氯苯硫醇。类似地,由9经由2-氯-6-[[(4-氯苯基)硫代]苯甲酸(11)制备1,7-二氯-9 H-噻吨黄酮-9(6)。还通过在硫酸存在下使2-氯-6-巯基苯甲酸(12)与氯苯缩合来获得化合物6。
