A new multidentate ligands 1,1,2,2-tetrakis {(2-benzylthio) ethylthio} ethylene (L 1 ) ; 1,1,2,2-tetrakis {(3benzylthio) propylthio} ethylene (L 2 ) ;1,1,2,2-tetrakis {2-(o-tolylthio) ethylthio} ethylene (L 3 ) ;1,1,2,2-tetrakis {3-(otolylthio) propylthio} ethylene (L 4 ) ; 1,1,2,2-tetrakis {2-(4-chloro-pheny-lthio) ethylthio} ethylene (L 5 ) ;(More)
A new type of organic salts and their ionic salts have been recently the subject of intensive research or the extractive desulfurization of model oil (DibenzothiopheneDBT), due to the limitation of hydrodesulfurization process for removing thiophenic sulfur compounds catalytically. This study is to investigate the possible application of the above compounds(More)
A new tetradentate carboxylic acid derivatives ligands, 1,4,8,11-tetraoxacyclo pentadecane-5,7,12,15tetrone(L 1 ) and 1,4,9,12-tetraoxacycloteptadecane,5,8,13,17-tetrone(L 2 ) were synthesized by condensation of 1,2dibromoethane with disodium succinic acid or disodium glutaric acid. Their complexes with Co(II), Ni(II), Cu(II) and Zn(II) have been(More)
Two new tetradentate ligands (L1 and L2) N,N'-bis {(o-aminophenylthio)bromo propyl} 1-phenyl butane 1,3-dilidene (L1), N, N'-bis (3bromo propyl (phenylthio) imino)1,1,1-trifluoro -3-(2-theonyl) acetone (L2) were prepared from the reaction of equimolar amount of (o-aminophenylthio) propylebromide and benzoylacetone or 2theonyltrifluoro acetone in (2:1) molar(More)
