Some new iodine heterocycles, 3,6-dinitro-dibenzo-Pyrroiodonium(Ⅲ)(p,p'-dinitro-diphenylene iodonium),3,6-dicyano-dibenza-Pyrroiodonium(Ⅳ)(p,p'-dicyano-diphenylene iodonium),3,6-dicyano-dibenzopyriodonium(Ⅴ),3,6-dinitro-9-(P-nitrophenyl)dibenzopyriodonium.(Ⅵ),3, 6-dicarboxy-dibenzo-pyriodonium(Ⅶ),3-nitro-dibenzo-pyrioonium-6-sulfonate(Ⅷ)(betaine form), 3,6-dinitro-dibenzo-heptaiodonium(Ⅸ)(with seven memner ring)3,6-dinitro-dibenzo-p-oxo-pyriodonium(Ⅹ), 3-nitro-dibenzo-p-oxo-pyriodonium-6-sullfonate(Ⅺ)(betaine form)and 3-nitro-6-carboxy-dibenzo-p-oxo-pyrdonium (Ⅻ)salts were found to be readily synthesizsd with the method as that one of the authours had been previously reported for preparing 3,6-dinitro-dibenzo-pyriodonium(Ⅰ)salts. 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.
