Read MoreABSTRACT The synthesis and characterization of five new linear diazaphenoxazine compounds is reported. The key intermediate, 3-chloro-1-9-diazaphenoxazine, was prepared via a base catalyzed reaction of 2-amino-3-hydroxypyridine with 2,3,5-trichloropyridine in aqueous 1, 4-dioxane. Five 3-amino…
Read MoreABSTRACT The removal of Pb(II) ions from aqueous model solution using zeolite has beeninvestigated under different operational parameters like heavy metal ionconcentration, adsorbent amount and particle size. The zeolite used wassynthesized and characterized using SEM…
Read MoreABSTRACT 3,5-Bis[(2-hydroxy-benzylidene)-amino]-benzoic acid (H2B) and itscobalt(II) and nickel(II) complexes were synthesized and characterized via:electronic, IR, 1H NMR and 13C NMR. Job’s continuous variation method wasused to determine the mole ratio for both metal complexes. Solvent…
Read MoreABSTRACT The synthesis of N-heteroaryl substituted benzene sulphonamides and evaluation of their biological activities are reported. Synthesis was achieved by the reaction of benzene sulphonyl chloride and substituted amino heterocycle in dry pyridine. The structures of…
Read MoreABSTRACT In this study, a series of N-pyridin-3-yl substituted [phenylsulphonamido] acetamide has been synthesized. The reaction of phenylsulphonyl chloride with various amino acids in basic medium yielded phenylsulphonamido alkanoic acid which, on chlorination with thionyl chloride,…

The organic electrophiles; N,N’-(2-dichloroethyl) piperazine-4-carboxi-amine, N-(2-chloroethyl) morpholine-4-carboxi-amine, and…
Read MoreABSTRACT Palladium catalysed synthesis of substituted 2-[acetyl(phenylsulphonyl)amino]-3-methylbutanamide (176) is reported. The intermediate 2-[acetyl(phenylsulphonyl)amino]-3-methybutanamide (175) was obtained by the reaction between 2-[acetyl (phenylsulphonyl)amino]-3-methybutanoic acid chloride (175) and ammonia. Substituted 2-[acetyl (phenylsulphonyl)amino]-3-methylbutanamides (176a-f) were obtained by coupling 2-[acetyl (phenylsulphonyl)amino]-3-methylbutanamide (175) with various readily available substituted aryl halides…
