Physicochemical properties of benzoic acid N,N-dialkylhydrazides
摘要:
Benzoic acid N,N-dialkylhydrazides of the general formula C6H5C(O)NHNR2, R = C4H9, C6H13, C8H17, C10H21, were obtained,. Their solubility, acid-base properties, stability against hydrolysis, distribution between organic and water phases were studied.
Reductive Alkylation of Hydrazine Derivatives with α-Picoline-Borane and Its Applications to the Syntheses of Useful Compounds Related to Active Pharmaceutical Ingredients
ingredients of therapeutic drugs such as isocarboxazid. An efficient method for the direct reductive alkylation of hydrazine derivatives with α-picoline-borane has been developed to synthesize a variety of N-alkylhydrazine derivatives. This method provided N,N-dialkylhydrazine derivatives and N-monoalkylhydrazine derivatives upon fine-tuning of the substrates and the reagent equivalency in a one-pot manner
Herein, we report a diaminocyclopentadienone ruthenium tricarbonyl complex-catalyzed synthesis of mono- or dialkylated acyl hydrazide compounds using the borrowing hydrogen strategy in the presence of various substituted primary and secondary alcohols as alkylating reagents. Deuterium labeling experiments confirm that the alcohols were the hydride source in this cascade process. Density functional

The solubility and acid-base properties of benzoic acid N,N-dihexylhydrazide(BDHH) were studied. The extraction of copper( II), cobalt(II), nickel(II), zinc(II), iron(III), platinum( II), platinum(IV), chromium( III), chromium(VI), palladium( II), and molybdenum( VI) with this reagent was studied. It was shown that BDHH most efficiently extracts copper( II) from ammonia solutions and chromium(VI) from sulfuric acid solutions. In the extraction of copper(II), complexes with the [Cu(II)] : [BDHH] = 1 : 1 and 1 : 2 stoichiometries were found to form. The structure of the 1 : 2 complex was suggested proceeding from its IR spectra. A copper(II) extraction isotherm was plotted.
