A new series of Mn(1I)-anilide complexes have been prepared and chara¬cterized by elemental analysis, TGA and IR spectra. Electronic and EPR spectra indicate octahedral geometry around the MN(II) ion, where the solvent ...

Differential pulse polarographic analyses were carried out on the hydroxylated anthraquinone contents of various Rumex species growing in Turkey. Alizarin and emodin, which were extracted both from the roots and aerial ...

Sulphamethoxyazole-N1 -(methyl 2,3,4-tri-O-acetyl-6-D-glucuronide) was successfully synthesized and characterized by NMR and mass spectrometry for the metabolic study of suiphamethoxazole.

Michael condensation of 1[p-bromopheny1]-34p-chlorophenyli-propen¬1-one [I] with ethyl cyanoacetate in the presence of ammonium acetate leads to the formation of (II) 6[p-bromopheny1]-2-hydroxy-44p-chlorophenyll nico¬tinonitrile, ...

Charcoal obtained from walnut shells were studied for determining the acidic surface complexes by selective neutralization technique using bases of different strengths. Effect of time, benzene extraction and demineralization ...

Condensation of 4-substituted-but-3-en-2-ones (1) with ethyl oxalate gave ethyl 6-aryl-2,4-dioxo-A2-hexenoates (2) and were interconverted to the methyl esters by alcoholysis. Compounds (2) were converted by hydrazine or ...

Xylenol orange reacts with mercuric acetate, chloride and iodide in non polar and polar medium to give mercurated products. Their structures are confirmed by analytical data, IR, UV/V and MS spectra. The halochromic effects ...

Dibenzoylmethanemono(tosylhydrazone) undergoes cyclisation reaction with butyllithium and lead tetraacetate to afford 3,5-diphenylpyrazole in good yield in both cases. Mechanistic schemes have been postulated to account ...
