The intermediate,potassium 4-nitro-diphenyl-methane-4'-sulfonate, m.p.267°(decomp.), for synthesizing betaine form of heteraiodonium compound(Ⅷ) is a new compound, which was prepared as the usual by sulfonation of 4-nitro-diphenyl-methane.The melting points with decomqosition of the new heteroiodonium salts were summarized as follows.Bisulfate Ⅲ, 278°; chloride Ⅲ,287—8°;bromide Ⅲ,283°;iodide Ⅲ 200.5°;thiocyanate Ⅲ,197°; prorate Ⅲ, 294°;bisuifateⅣ, 263°; chloride Ⅳ, 292°;bromide Ⅳ, 265°; rodide Ⅳ, 208°;thiocyanate Ⅳ,202°; bisulfate Ⅴ, 236°;chlorideⅤ, 233°;bromide Ⅴ, 214—5°;iodide Ⅴ, 177—8°;thiocyanate Ⅴ,207—9°;bisulfate Ⅵ,237°;chloride Ⅵ, 176.5°;bromide Ⅵ,178.5—9.5.iodide Ⅵ, 151—2°;thiocyanate Ⅵ, 185—7°;bisulfate Ⅶ, 244—5°; chloride Ⅶ, 240°;betaine Ⅷ, 255°; chloride Ⅸ, 197—8°;thiocycanate Ⅸ,172—3°;picrate Ⅸ, 171—2°;bisulfate Ⅹ,232°; chloride Ⅹ, 246°;bromide Ⅹ,245°;iodide Ⅹ, 160°;thiocyanate Ⅹ,167—8°; betaine Ⅺ,284°; bisulfate Ⅻ, 233.5°;bromide Ⅻ, 225°. Iodid;Ⅲ,Ⅴ and Ⅹ decomposed at their melting points to give 2,2'-diiodo-4, 4'-dinitro-biphenyl(ⅩⅢ),m.p. 145—6°, 2, 2'-diiodo-4, 4′-dicyano-diphenyl methane(ⅩⅣ),m.p.124—5"(solidified at 148°,and re-melted at 231.5°), and 2,2'-diiodo-4,4'-dinitrodiphenylether(ⅩⅤ), m.p.165—7。 3,6-Dinitro-9-(p-nitrophenyl-)dibenzo-pyriodonium(Ⅵ) salts gave a deep bluish coloration, the similar behavior as what was known for 3,6-dinitro-dibenzo-pyriodonium(Ⅰ) salts as reported previousiy, when treated with sodium hydroxide solution or with pyridine. Betaine Ⅷ gave a pale bluish coloration when it was heated with pyridine.The UV-spectra of thiocyanate Ⅵ in pyridine gave a peak at λmax.623 mμ(log ε 4.21),which was stable for 18 hours duration,and of thiocyanate Ⅰ,λ max.730 mμ(log ε 4.20),the intensity of which was lowered (log ε 3.30)and developed a new peak,λmax,630 mμ(log ε3.79)after stand for half an hour, and both these twopeaks were varnished after 17.5 hours duration.However, such phenomena of coloration could not be found for the heterocyclic iodo num salts indicated above other than Ⅰ,Ⅵ and Ⅷ. Oxford cup Test revealed that bisulfate Ⅰ, chloride Ⅴ,chloride Ⅸ and bisulfate Ⅹ inhipited The growth of B.subtilis. The preiiminary pharmaceutical observations of formate Ⅱ,reported previously,revealed that it possessed an intense hypotensive action to rabbit. Under the same conditions mentioned above, reaction between 4,4-dinitro-diphenyl-thioether and iodosyl sulfate yielded 4, 4'-dinitro-diphenylsulfone,and could not any heterocyclic compound containing both iodine and sulfur be obtained.

In view of the effectiveness of bis(3,5-dichloro-2-hydroxyphenyl) sulphide (Bithionol, Ⅱ_b) in the treatment of human paragonimiasis and its protective action against the cercariae of Schistosoma mansoni, a series of analogous compounds was prepared in the present work for pharmacological examinations. 2,2'-Dihydroxy-5,5'-diphenyl sulphide (Ⅱ_a) was chlorinated by means of tert-butyl hypochlorite, or brominated by means of either bromine or N-bromosuccinimide, giving mono- or di-substituted derivatives. The compounds substituted with mixed halogens were prepared by bromination of the corresponding chloro-componnds. Many of such phenolic compounds were also acetylated, benzoylated or etherified, and compounds carrying various side chains of acyloxy, alkoxy or 2-diethylamino-ethoxy linkages were afforded. Since these compounds have a wide range of physico-chemical properties, it is expected that their pharmacodynamic properties would also be different. Preliminary pharmacological examinations revealed that bis (3,5,6-trichloro-2-hydroxyphenyl) sulphide (Ⅳ_a) was quite active against Schistosoma japonicum, and bis(3-bromo-5-chloro-2-hydroxyphenyl) sulphide (Ⅱ_c) was less active.
