The reaction between H2NCSNH2 (I) and PhN(Me)NO (II) in aqueous acid solution gave PhNHMe (III) and a S-nitroso intermediate (IV) which decomposed to form [(H2N)2C+S]2. The latter two products are the same as those from the reaction of I and HNO2. The nitrosoamine reaction was acid-catalyzed and was first order in both I and II. Added III reduced the reaction rate, showing that the formation of IV was reversible, i.e. it was capable of acting directly as a nitrosating agent. The reactivities (relative to III) of ‘various nitrite’ traps (NH3, H2NN+H3, H2NSO3H, H3N+OH, urea) towards IV were determined, the order of reactivity was the same as for the nitrosating agents NOCl, NOBr, and H2N+O2, but discrimination by IV was greater than for these, implying that IV is a less reactive species. Rate constant ratios obtained for NOSCN are similar to those of IV suggesting that they have almost the same reactivity as nitrosating agents.

The cell constants and space groups of some cyanine dyes and their solvates were determined The structure of the unsolvated dye 3,3′-diethylthiacarbocyanine bromide was elucidated from 2 projections. The cation is planar with the conjugated chain in the extended form. The S atoms are cis with respect to this chain. Some curious properties of the crystals are described. The results of the structure determination are correlated with other properties of cyanine dyes.

Walker, James B. published the artcileFurther studies on the mechanism of transamidinase action: transamidination in Streptomyces griseus, Recommanded Product: Formamidine disulfide dihydrochloride, the publication is Journal of Biological Chemistry (1958), 1-9, database is CAplus.

cf. C.A. 51, 8169d. In contrast to mammalian kidney transamidinase, that of S. griseus does not react with glycine. Like the kidney transamidinase, it catalyzes reversible arginine-ornithine and canavanine-ornithine transamidinations. The concept of an enzyme-amidine intermediate in transamidination reactions is supported by (a) the occurrence of the arginine-ornithine exchange reaction, coupled with specificity considerations, and (b) the fact that the formamidine moiety of the intermediate can be trapped with HONH₂ to form hydroxyguanidine. Formamidine disulfide is a potent inhibitor of transamidinase. It is suggested that its inhibitory action results from the formation of a mixed disulfide with an essential sulfhydryl group on the enzyme. A sensitive colorimetric assay for hydroxyguanidine is described.

I (X = Cl) was the most stable and I (X = iodine) the most labile, liberating iodine. I was soluble in H₂O but not in organic solvents. Addition of organic solvent to the solution of I (X = iodine) immediately started liberation of iodine.

Sahasrabudhey, R. H. published the artcileThiocyanamides and sulfonitriles: their constitution and identity, SDS of cas: 14807-75-1, the publication is Journal of the Indian Chemical Society (1950), 524-6, database is CAplus.

Thiocyanamide-HCl (I) was made from “amidothiotriazole” (II) by the Freund and Schander procedure [Ber. 29, 2500(1896)]. Oliveri-Mandalà (C.A. 9, 71) showed the “amidothiotriazoles” were really thiocarbamic acid azides; he made the HCl salts of phenyl-, tolyl-, and ethylthiocarbamic acid azides and the salts of the corresponding thiocyanamides, which he called sulfonitriles. I has saline characteristics, shown by its solubility in H₂O and alc. and insolubility in ether, CHCl₃, CCl₄, and C₆H₆. Aqueous solutions were highly acid because of hydrolysis. The free base could not be isolated, but addition of alkali precipitates S, and thiourea and NH₂CN are formed in solution Thiocyanamide salts liberate iodine from aqueous KI solutions Reduction of I in H₂O with Zn and HCl evolved large quantities of H₂S, and when a portion treated with excess NaOH solution gave no precipitate of S, absence of unreduced thiocyanamide was indicated. The remainder was made ammoniacal, the Zn precipitated as ZnS with H₂S, and filtered; the filtrate on concentration deposited crystals of thiourea in a sirupy residue of NH₂CN. Thiocyanamide salts: nitrate, m. 82° or 140° (decomposition); picrate, m. 154° or 164° (decomposition); HBr salt, m. 185-90° (decomposition); HCl salt, m. 186° (decompose). The m.ps. were identical with, and did not depress, those of the corresponding salts of [H₂NC(:NH)S]₂ (II) (Proc. Indian Sci. Congress, 1948, Pt. III, p. 25). Formation of thiocyanamide from H₂NCSN₃ and the identity of its empirical composition with that of II (HCl salt, CSN₂H₄Cl (?)), the oxidation product of thiourea suggests that they may be identical. The constitution is still being investigated. The aromatic thiocyanamides or sulfonitriles can not be the same as the corresponding formamidine disulfides because the aryl derivatives of the latter are known not to exist, while the free bases from the salts of the former have been made and the mol. weights determined O.-M. (C.A. 17, 738) suggested pentacovalent N structures, which is untenable. Fischer and Besthorn [Ann. 212, 316(1882)] and Hugershoff [Ber. 36, 3134(1903)] say that they are the same as the corresponding 2-aminobenzothiazoles. Comparison of m.ps. given by O.-M. (C.A. 9, 71) with corresponding arylaminothiazoles almost proves identity. Aniline sulfonitrile, C₇H₆N₂S, m. 122-3°, 2-aminobenzothiazole, C₇H₆N₂S, m. 123°; ο-toluidine sulfonitrile, C₈H₈N₂S, m. 138-40°, 2-amino-4-methylbenzothiazole, C₈H₈N₂S, m. 140°.

E. published the artcileElectrochemical response of thiourea and formamidine disulphide on polycrystalline platinum in aqueous 0.5 M sulphuric acid, Application of Formamidine disulfide dihydrochloride, the publication is Journal of Electroanalytical Chemistry (1999), 475(2), 181-189, database is CAplus.

The electrochem. response of both thiourea and formamidine disulfide dissolved in aqueous 0.5M sulfuric acid on polycrystalline platinum electrodes was studied at 298 K, using voltammetry and rotating ring-disk electrode techniques. The electrooxidation of thiourea on platinum involves two stages occurring in different potential windows. The 1st thiourea electrooxidation stage for E<0.7 V (vs. SCE), yielding soluble formamidine disulfide as the main product, behaves as an electrochem. process under intermediate kinetics. Kinetic parameters for the electrooxidation of thiourea are estimated The voltammetric electroreduction of formamidine disulfide dihydrochloride to thiourea is inhibited gradually by the adsorption of byproducts from the electrochem. reactions. The 2nd thiourea electrooxidation stage for E 0.7 V involves the oxidation of thiourea and adsorbed residues competing with the oxide monolayer formation on platinum.
