    Notes: Synthesis and Reaction Behaviour of N-(3-Chlorobenzo[b]thiophene-2-carbonyl)-imino-dithiocarbonic Derivatives3-Chlorobenzo[b]thiophene-2-carbonyl-chloride 1 was treated with potassium rhodanide to afford the appropriate acyl isothiocyanate 3, which adds nucleophilic agents as amines and thioles in good yields.Addition of methanethiole and subsequent alkylation of the dithiocarbamate 7 gives S, S-dimethylimino-dithiocarbonate 8. 3-Chlorobenzo[b]thiophene-2-carboxamide 2 reacts with carbon disulphide and phenyl isothiocyanate by chlorine substitution and cyclisation to benzo[b]thieno[2, 3-e]thiazines 9, 10 or 11. The structure of the final products were determined by analytical and spectroscopical dates.

    Notes: Reaction Behaviour of Amides with Carbondisulphide and IsothiocyanatesReactions of substituted arylamides, hetarylamides and furylacrylicamide 1 with carbon disulphide present a possibility to synthesize imino-dithiocarbonic-S,S′-diester 5. The mechanism of the reaction and the reaction conditions are investigated. Quantum chemical investigations by simple HMO-method in connection with the experimental results describe the reaction in dependence upon the influence of substituent in 2- and 4-position to the phenylring. Further more is described the reaction of amide with isothiocyanates to thiourea 6 and isothiourea 7.The structures of the final products are determined by analytical dates.

    Die Adsorption von Chlorid an einem austenitischen Cr-Ni-Stahl bei hohen Temperaturen (1988)

    Description / Table of Contents: The adsorption of chloride on austenitic Cr-Ni-steel at high temperaturesUsing the radioactive isotope chlorine-36 and nuclear physical measuring methods (gas-flow radiation detector, autoradiography) chloride adsorbed on metal surfaces can be detected with a detection limit of 10-10 g cm-2 and a local resolution of at least 5 μm. This method was developed for investigating the chloride adsorption on the protective layers on an austenitic Cr-Ni-Steel (X 8 CrNiTi 18.10) under high temperature conditions at 250°C. Three different kinds of chloride adsorption could be distinguished: homogeneous chloride distribution across the whole surface, high localized chloride concentrations in places of local corrosion attack and local deposition of chloride by heat and mass transfer. The results obtained enabled attack concepts for the mechanism of action of the chloride were derived. Potential applications of this method to the rapid detection of chlorideinduced corrosion processes (pitting corrosion, stress corrosion cracking or crevice corrosion) or to the quantitative estimation of thermohydraulic concentration processes are mentioned.
    Notes: Durch Verwendung des radioaktiven Isotops Chlor-36 und kernphysikalischer Meßmethoden (Gasdurchflußzählrohr, Autoradiographie) kann an Stahloberflächen adsorbiertes Chlorid mit einer Nach-weisgrenze von 10-10 g/cm2 bei einem lokalen Auflösungsvermögen von mindestens 5 μm nachgewiesen werden. Diese Methode wurde benutzt, um die Chloridadsorption an den Schutzschichten eines austenitischen Cr-Ni-Stahls (X 8 CrNiTi 18 10) bei hohen Temperaturen (250°C) zu untersuchen. Dabei konnten drei unterschiedliche Arten der Chloridadsorption festgestellt werden: gleichmäßig flächenhafter Belag, hohe, örtlich begrenzte Chloridkonzentration an Stellen des lokalen Korrosionsangriffs und lokale Anreicherung von Chlorid durch Wärme- und Stofftransportvorgänge. Aus den Ergebnissen wurden Vorstellungen zum Wirkmechanismus des Chlorids abgeleitet. Auf die Anwendungsmöglichkeiten der Methode zum schnellen Nachweis eines chloridinduzierten Korrosionsprozesses (Lochfraß-, Spannungsriß- oder Spaltkorrosion) bzw. zur quantitativen Bewertung von thermohydraulischen Anreicherungsprozessen wird hingewiesen.

    Notes: Reactions with N-Acylimino-dithiocarbonic-acid-diesters.Reactions of N-acylimino-dithiocarbonic-acid-S,S-diesters 1 with nucleophilic com-pounds present new possibilities to synthesize heterocycles. With amines 1a reacts by mono- and disubstitution, respectively, of methylthio-groups to isothioureas 2 and guanidines 3, with 1,2-bi-nucleophilic arenes to benzoheterocycles 4, with aliphatic diamines to imidazolidines 5, pyrimidines 6, diazepines 7 and the hexamethylene-diamine-derivatives 8. 1a reacts also with hydrazines to 1,2,4-triazoles 9 and with hydrazides to the thiosemicarbazones 10 or 1,3,4-oxadiazoles 11. Heterocyclisations of 1 with guanidines, thiourea, salts of thiourea and amidines give the 1,3,5-triazines 12, 14, 15 and 16. N-benzoyl-dithiocarbonic-acid-methylester -amid reacts with CH-acidic compounds to thiazoles 17. The structures of the final products are determined by i.r.-, 1H-n.m.r.-, u.v.- and mass-spectras.

    Notes: New Synthesis of Dimethyl-cinnamoylimino-dithiocarboxylate and Reactions with NucleophilesA new general synthesis of dimethyl-cinnamoylimino-dithiocarboxylate 1d is possible by reaction of 4-nitro-cinnamoylamide with carbon disulfide in the presence of sodium hydride and following alkylation. With the unsubstituted dimethyl-cinnamoylimino-dithiocarboxylate 10 is in-vestigated the reaction behavior with nucleophilic compounds. The treatment of 1c with primary amines, respectively, by mono- and disubstitution of the methylthio groups yields isothiourea 2 or guanidines 3. Benzocondensed heterocycles are formed by reaction of 1c with o-bifunctional nucleo-philes.The compounds 5, 6 and 7 have been synthesized from 1c with cysteamine, p-phenylenediamine and ethylenediamine.The oxadiazole 8 and isothiosemicarbazide 9 are obtained by reaction of the dithioester 1c with hydrazides. On the other hand cyclisation to the 1,2,4-triazole 11 over the intermediate 10 and to the 1,3,5-triazine 12 are possible.The reaction of 1c with carbanions in a basic medium affords acrylic derivatives 13.In the same way we isolated by reaction of dithioester 1c with a benzothiazolium salt the dark coloured compound 14. The physical properties of synthesized compounds are discussed by mass-, 1H-n.m.r.-, i.r.- and u.v.-spectra.
