THE PRODUCTION OF CLASS-II MIXED-VALENCE COMPLEXES IN THE REDOX REACTION BETWEEN DITHIOMALONAMIDE AND PLATINUM(IV) OR PALLADIUM(IV).

Due to its joint reducing and complexing properties, dithiomalonamide (HL) reacts with 6>2- and 6>2- ions to afford two types of complexes which, on the basis of microanalytical data, may be formulated as M(HL)X3 and M(HL)2X3 respectively.A detailed investigation of their behaviour in solution (1H, 13C, and 195Pt n.m.r.) and in the solid state (i.r., visible, x.p.s., and electrical conductivity measurements) has been performed.The experimental data show the two types of complexes to be mixed-valence compounds which are best formulated as II(HL)2>IVX6> and II(HL)2>IV(HL)2X2>X4 respectively.In these complexes, dithiomalonamide co-ordinates to palladium and platinum either via SN or S2 donation.They are recognised as semiconductors with electrical conductivities up to 10-4 Ω-1cm-1.

Method for synthesizing quaternary ammonium salt -73

The invention relates to the technical field of chemical synthesis, and provides a synthesis method of quaternary ammonium salt -73, which comprises the following steps: (1) thionamide generation thioreaction, and obtaining a compound of formula (I). (2): The compound of formula (I) reacts with chloroacetone to yield the compound of formula (II). (3) The compound of formula (II) is desalted, and the compound of formula (III) is obtained after dehydrogenation and iodoheptane in the presence of an organic solvent. (4) Of formula (III) and iodoheptane are reacted to give the compound of formula (IV), i.e. the quaternary ammonium salt -73. The preparation method has the advantages of cheap and easily available raw materials, simple operation, controllable reaction process, easy separation and purification of the product, high total yield, high purity and suitability for industrial scale production.

Cyanoselenoacetamide in a new synthesis of propane-bis(thioamide), the promising reagent for heterocyclizations

Cyanoselenoacetamide reacts with hydrogen sulfide to form propane-bis(thioamide), which can be used to produce thiazoles (the Hantzsch synthesis) and 3-thioxo-1-phenyl-2,3,5,6,7,8-hexahydroisoquinoline-4- carbonitrile. From the latter compound, 2-alkylsul

A mild and versatile synthesis of thioamides

Aliphatic and aromatic nitriles react with thioacetic acid in the presence of calcium hydride to give the corresponding thioamides in good to excellent yields. The examples studied include haloaryl nitriles in which the halogen is facile towards SNAr reactions under other conditions. Georg Thieme Verlag Stuttgart.

Hetero-calix[4]pyrroles: Incorporation of furans, thiophenes, thiazoles or fluorenes as a part of the macrocycle

Furans, thiazoles, fluorene or thiophene incorporated calix[4]pyrrole analogues were synthesized and characterized. The synthesis was achieved by utilization of various building blocks such as 7, 13, 14, 18 and 21. Acid catalyzed condensation of those building blocks with acetone or meso-disubstituted dipyrromethanes afforded desired macrocycles.

Synthesis of primary thioamides from nitriles and hydrogen sulfide catalyzed by anion-exchange resin

A new method has been developed for converting nitriles into primary thioamides. Treatment of various nitriles (Table 1, entries 1-12) with gaseous hydrogen sulfide in a mixture of methanol-water or ethanol-water and in the presence of anion-exchange resin (Dowex 1X8, SH- form) at room temperature and ambient pressure gave the corresponding thioamides in 25-96% yield.

DIHETEROARYLMETHANES. II. ACTIVE METHYLENE BEHAVIOUR OF 2-THIAZOLYL AND 2-OXAZOLYL DERIVATIVES

The methylene group of bis(2-benzothiazolyl)methane (bbtmH), 1, bis(2-benzoxazolyl)methane (bbomH), 2, and bismethane, 3, undergoes azo-coupling with benzenediazonium chloride to the corresponding phenylhydrazono derivatives, nitrosation with nitrous acid to the corresponding oximes, and crotonic-type condensation with alkyl, aryl, and heteroaryl aldehydes.In the condensation of bbomH, 2, with salicylaldehyde, one of the benzoxazole moieties undergoes ring opening and the final product is a coumarin derivative.The methylene group of 1 and 3 is also sensitive to oxidation by air in alkaline solution leading to the corresponding carbonyl compounds 15 and 17.The analogous reaction carried out on bbomH was found to be sluggish.The behaviour of these diheteroarylmethanes thus conforms with the one typically exhibited by "active" methylene compounds, substituted by efficient electron-withdrawing groups.

STUDY OF DIRECTION OF CYCLIZATION OF MALONODITHIOAMIDES AS A METHOD OF INVESTIGATION OF REACTIVITY OF α-DIAZOTHIOACETAMIDES

The reaction of malonothioamides with benzene-sulfonyl azide and 2-azido-3-ethylbenzthiazolium tatrafluoroborate gave amides of 2-diazothiomalonic acid, which underwent cyclization to a mixture of 5-N-R-amino-1,2,3-thiadiazole-4-carbothioamides and 5-amin

TWO DIRECTIONS OF CYCLISATION OF α-DIAZO-β-DITHIOAMIDES. NEW REARRANGEMENTS OF 1,2,3-TRIAZOLE-4-CARBOTHIAMIDES.

The cyclization processes of 2-diazomalondithioamides, generated by five different methods, have been studied.The ambient character of the derivatives of 2-diazomalondithioamide is the cause of previously unknown rearrangements of 5-mercapto-1,2,3-triazole- and 5-amino-1,2,3-thiadiazole-4-N-R-carbothioamides to 5-N-R-amino-1,2,3-thiadiazole-4-carbothioamides.NMR 1H and 13C spectra and mass-spectra are presented for the series of 5-amino-1,2,3-thiadiazole derivatives.
