N′-(3-Ethoxy-2-hydroxybenzylidene)benzenesulfonohydrazide
There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(4)S, both of which are stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds lead to [101] chains of mol-ecules in the crystal structure.
متن کامل4 - Chloro - 6 - ethoxy - 2 - ( methylthio ) pyrimidine
4,6-Dichloro-2-(methylthio)pyrimidine (3) reacts with EtONa in EtOH, at ca. 20 ◦C, for 2 h, to give exclusively 4-chloro-6-ethoxy-2-(methylthio)pyrimidine (5) in 89% yield. The latter is presented as a useful multifunctionalised pyrimidine scaffold.
متن کاملDirect Spectrophotometric Determination of Ni (II) Using 5- Bromo-2- hydroxyl -3-methoxybenzaldehyde-4-hydroxy benzoichydrazone
: A rapid, simple,sensitive and selective direct spectrophotometric method has been developed for the determination of nickel(II) in various real samples. 5-Bromo-2-hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic hydrazone reacts with Ni(II) forming green coloured soluble complex [ ( Ni(II)-5-BHMBHBH] in basic buffer solution. The maximum absorbance was observed in the pH range 5.5-7.5 and Ni(I...
متن کاملEnzyme-Catalyzed Synthesis of Water-Soluble [1.0]Conjugated Poly[2-(3-thienyl)-Ethoxy-4-Butylsulfonate]
An environmentally friendly water-soluble conjugated polythiophene poly[2-(3-thienyl)ethoxy-4-butylsulfonate] (PTEBS) has been found to be effective for making hybrid solar cells. In this work, we first report the enzyme-catalyzed polymerization of (3-thienyl)-ethoxy-4-butylsulfonate (TEBS) using horseradish peroxidase (HRP) enzyme as a catalyst and hydrogen peroxide (H2O2) as an oxidant in an ...
متن کامل2-Hydroxy-3-methoxybenzaldehyde 2,4-dinitrophenylhydrazone pyridine monosolvate
The Schiff base molecule of the title compound, C(14)H(12)N(4)O(6)·C(5)H(5)N, was obtained from the condensation reaction of 2-hy-droxy-3-meth-oxy-benzaldehyde and 2,4-dinitro-phenyl-hydrazine. The C=N bond of the Schiff base has a trans arrangement and the dihedral angle between the two benzene rings is 3.49 (10)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, ...
