N-Salicylideneamino acidato complexes of oxovanadium(iv). The cysteine and penicillamine complexes

Magnetic property and crystal structure of bis [N-(4-chlorophenyl) salicylideneaminato] oxovanadium (IV)

“…These properties for the vanadium complexes are applied to many scientific fields, for example, catalytic chemistry [2], bioinorganic chemistry [3], electrochemistry [4,5] and molecule-based magnetism [6][7][8][9][10][11][12][13][14]. There are numbers of papers for the tetravalent vanadium complexes which have strong vanadium-oxygen multiple covalent bonds [15,16].…”

Synthesis, crystal structures, spectroscopic characterization and in vitro antidiabetic studies of new Schiff base Copper(II) complexes

“…Similar to complex 1, positive bands at 228 and 253 nm and negative bands at 211 and 278 nm were observed for complex 2, except a negative band at 240 nm. 37 Further, the relative intensities of these bands are different between complex 1 and 2. The difference in the CD spectrum could be attributed to the difference in the structure of complexes 1 and 2.…”

Preface: Recent Advances and Highlights of the 5th International Vanadium Symposium

“…Aldol-type condensations have been carried out in the presence of vanadium (27), as well as Michael-type base-catalyzed additions (28) and asymmetric hetero Diels-Alder reactions (29). Several other vanadium mediated C-C bond formation reactions have also been reported (30), e.g., oxidative coupling of phenols, naphthols and arenes, asymmetric synthesis of BINOLs, Mannich-type (37) and modified Mannich-type reactions.…”
