N,N'-Dinitrourea reacts with bases to form the corresponding acid or neutral salts. Its reaction with hydrazine yields 4-nitrosemicarbazide, and the reaction with hydroxylamine leads to N-hydroxy-N'-nitrourea. 相似文献

The reactions of oxygen with a series of dihydropyridazines have been explored. The primary reaction other than aromatization appears to occur from the 1, 4-dihydro tautomer. A single crystal x-ray structure has been determined on the product from the reaction of oxygen with 3, 6-diphenyl-4, 4-dimethyl-1, 4-dihydropyridazine. 相似文献

Effects of Aminophenol Derivatives on Radiation-Induced Reactions Involving Various Organic Radicals
G. A. Ksendzova V. L. Sorokin I. P. Edimecheva O. I. Shadyro 《High Energy Chemistry》2004,38(6):364-368
The effects of some aminophenol derivatives, diphenylamine, and ionol on the formation of ethanol and hexane radiolysis products in aerated and deaerated solutions were studied. The results allowed conclusions to be made about the effect of the structure of test compounds on their reactivity to oxygen- and carbon-centered radicals. It was found that 4,6-di-tert-butyl-2-(N-acetylamino)phenol, 4,6-di-tert-butyl-2-(N-benzoylamino)phenol, 2-hydroxydiphenylamine, and 4-hydroxydiphenylamine were highly competitive with commercial antioxidants in the efficiency of inhibition of radiation-induced processes of hexane oxidation. N-(2-Hydroxy-3,5-di-tert-butylphenyl)aniline, 4,6-di-tert-butyl-2-cyclohexylaminophenol, 2-hydroxydiphenylamine, 4-hydroxydiphenylamine, and N-phenyl-1,4-benzoquinonemonoimine were superior to ionol and diphenylamine in the inhibition of reactions of alkyl and -hydroxyalkyl radicals. 相似文献

Pentaphenylantimony and -phosphorus react with arylmercury chlorides in toluene at room temperature to give diaryl derivatives of mercury in yields of up to 95%. The reactions of pentaphenylantimony and -phosphorus with silicon and tin halides involve arylation of the latter in yields of up to 79%. The products of the reaction of pentaphenylphosphorus with triphenylbismuth dihalides are tetraphenylphosphorus halides, triphenylbismuth, and halobenzene. 相似文献

Reaction of perfluoro-n-octanonitrile with diphenylphosphine gave two products: a primary adduct, C7F15C(NH)P(C6H5)2, and the reduced adduct, C7F15CH(NH2)P(C6H5)2. Presence of water prevented the formation of the reduced compound; the latter was not produced by reduction of the primary adduct. Operative mechanisms are postulated; infrared and mass spectra are discussed. 相似文献

By oxidative-addition of X2 (X = Cl, Br) to SnF2 in acetonitrile, monomeric SnF2Cl2(MeCN)2 and polymeric or oligomeric SnF2Br2(MeCN)2 are obtained. The corrected v CN IR frequencies provide a good indication of the Sn–N bond strength. The reactions of SnF2 with Br2 and I2 in the presence of DMSO, and with I2 in the presence of pyridine yield the disproportionation products rather than the mixed-halide compounds. That suggests that the stability of the mixedhalide compounds decreases when the difference between the halides increases. The reaction of SnF2 with I2 in acetonitrile gives rise to SnF4(MeCN)2, and provides a simple and inexpensive route to SnF4 and its complexes, as MeCN is lost under mild conditions or substituted by other ligands. In this way we have prepared SnF4L2 (L = DMF, DMSO, THF, Py). The structure of the compounds is discussed in terms of the IR and 119Sn Mössbauer spectra and, in the case of SnF4L2, the Mössbauer isomer shift and the IR v Sn–F compared to the corresponding SnCl4L2 compounds. 相似文献

Treatment of salicylaldehydes with acrylate derivatives in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) has been shown to afford both coumarin and chromene derivatives, and factors influencing the product distributions have been investigated. 相似文献

The reactions of SnF2and SbF3with NbCl5in acetonitrile or dimethyl sulfoxide were studied by 19F, 93Nb, and 119Sn NMR spectroscopy. The products of reaction in acetonitrile are anionic, while those in di-methyl sulfoxide are neutral octahedral niobium chlorofluoride complexes. Tin(II) difluoride and antimony(III) trifluoride are powerful sources of fluoride ions in the preparation of metal chlorofluoride and fluoro complexes. 相似文献

The chemical behavior of 1-adamantylnitrenium ion seems to be not known much compared to 1-adamantylcarbinyl cation,2 though one example of the rearrangement of 1-adamantylnitrenium ion to 4-azahomoacamantyl ion has been reported recently by Kovacic et al in the reaction of 1-M,N-dichloroaminoadamantane with aluminum chloride.3 From our interest in the reactivity and rearrangement aptitude of 1-adamantylnitrenium ion, we investigated the reactions of various N-substituted N-chloro-1-adamantylamine derivatives with aluminum chloride. This communication deals with the preliminary results which indicated that the reactions of 1-adamantylnitrenium ion are much affected by the N-substituents and also by the solvents used. 相似文献
