Electrocoagulation was used for dechlorophyllation of alcoholic extracts from five plants. The results showed that for every plant extract studied, electrocoagulation was more efficient than the classical solvent extraction method in removing plant p...

The title compound 6-amino-3-benzylmercapto-1,2,4-triazolo[3,4-f][1,2,4]-triazin-8(7H)-one (4), molecular formula C₁₁H₁₀N₆OS, was obtained by the reaction of3-amino-2-benzyl-6-hydrazino-1,2,4-triazin-5(2H)-one (3) with carbon disulfide in awater/pyri...

The syntheses of new chiral cyclic 1,2-diacetals from (2R, 3R)-( )-tartaric acidare described. C₂-symmetrical diamines were prepared via direct amidation of the tartrate orfrom the corresponding bismesylate via reaction with sodium azide. For C1-symm...

L-Proline catalyzed additions of 13 different thiols to 11 different α-enoneMichael acceptors in [bmim] PF₆ are reported. Reasonable to high yields of the reactionproducts were isolated in most cases.

Five novel Schiff bases have been prepared from o-formylphenoxyacetic acidand a series of aminothiazoles to form a number of potentially biologically activecompounds. The structures of these Schiff bases have been characterized using IR and ¹H-and ¹³...

A series of three para-benzoquinone mono-oximes and four oxy-derivatives were prepared and tested for their antidepressant properties. The (4E) oxime of 2-isopropyl-5- methyl-para-benzoquinone (4) and the corresponding 2-diethylamino-ethyl derivative...

(7-Hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide (2) was prepared from (7-hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid ethyl ester (1) and 100% hydrazine hydrate. Compound 2, is the key intermediate for the synthesis of several series of new com...

The nitro group of methyl 3-nitropyridine-4-carboxylate (1) has successfully been replaced by fluoride anion via nucleophilic aromatic substitution to give the 3-fluoro- pyridine-4-carboxylate 2.

The synthesis, spectroscopic characterization, and X-ray crystal structure ofthe sodium salt of a new sulfonated water-soluble ligand, sodium 2-(2-pyridin-2-yl-ethylamino)-benzenesulfonate (L) are described. Compound L crystallizes in thecentrosymmet...
