Mononuclear and dinuclear salen type copper(II) Schiff base complexes: Synthesis, characterization, crystal structures and catalytic epoxidation of cyclooctene

Mono, di and heptanuclear metal(II) complexes based on symmetric and asymmetric tetradentate Salamo-type ligands: Syntheses, structures and spectroscopic properties

“…Salen or Salen-type ligands are obtained by the reaction of salicylaldehyde or its derivatives with diamines, could coordinate to d-block transition metal ions used to obtain mono-and polynuclear metal complexes [6][7][8][9]. These metal complexes are used in excellent non-linear optical materials [10,11], unique biological systems [12] and interesting magnetic materials [13,14].…”

Schiff base complexes of Ni, Co, Cr, Cd and Zn supported on magnetic nanoparticles: As efficient and recyclable catalysts for the oxidation of sulfides and oxidative coupling of thiols

“…Recently, metal complexes of Schiff-bases have been emerged for the development of efficient variety of catalysts [7,10] however, to clean and facilitate catalysts separation, Schiff-base compounds have been supported onto heterogeneous materials [11,12]. Among them, salicylidene Schiff-base (salen) can be easily prepared using condensation of salicylaldehyde and amine groups.…”

Schiff base‐functionalized boehmite nanoparticle‐supported molybdenum and vanadium complexes: efficient catalysts for the epoxidation of alkenes

“…[1][2][3][4] In the last decade, several soluble Schiff base complexes of Cr, [4,5] Mo, [4,6,7] Re, [8] Ni, [9] Co, [10,11] Mn, [12,13] V, [14][15][16][17] Cu, [18] Ru [19] and Ti [20] have been employed as active homogeneous catalysts in the epoxidation of alkenes. However, most of these catalysts are expensive and contaminate the environment.…”
