An unprecedented heterotrimetallic Fe/Cu/Co core for mild and highly efficient catalytic oxidation of cycloalkanes by hydrogen peroxide

Direct template synthesis of a heterometallic CoIII/ZnII complex: The advantage of using a metal powder as a starting material

“…Due to outstanding kinetic inertness and stability of cobalt (III) amino complexes (for example, logb 3 for Co(en) 3 3+ = 48.71 [12]), their reaction with ace- [13]. The condensation reaction was explained by the formation of free NH 3 in the reaction mixture as a result of the NCO À anion hydrolysis.…”

“…At the same time it is a powerful tool to search for compounds with new molecular architectures that can possess useful magnetic and catalytic properties [2,3]. The anion deficiency as a result of using elemental metal assists deprotonation of protonic ligands and promotes formation of polynuclear species.…”

Copper(II) coordination polymers derived from triethanolamine and pyromellitic acid for bioinspired mild peroxidative oxidation of cyclohexane

“…A promising approach consists on the design and development of new bioinspired catalytic materials [10][11][12][13]. In this respect, particulate methane monooxygenase (pMMO) appears to be a unique copper enzyme that can catalyze the hydroxylation of alkanes.…”

Two novel Cu(II) complexes: Synthesis, structure and application in C–H bond activation

“…Nicola and his co-workers synthesized a Cu(II) complex [Cu 3 (l 3 -OH)(l-pz) 3 (EtCOO) 2 (H 2 O)] and found that it showed a good catalytic activity (the yield of main product is 28%) in Cy oxidation by H 2 O 2 with HNO 3 as additive in MeCN [16]. Nesterov and co-workers found that the Cu(II) complex [Cu 2 Co 2 Fe 2 (l-dea) 6 (NCS) 4 (MeOH) 2 ]Á3.2H 2 O (H 2 dea: diethanolamine) had potential catalytic activity for Cy and cyclopentane oxidation with H 2 O 2 in the presence of HNO 3 , and the yield is 45% and 36%, respectively [17]. Kirillov reported that the total yield is 39% when [Cu 4 (l 4 -O)(l 3 -tea) 4 (l 3 -BOH) 4 ][BF 4 ] 2 (H 3 tea: triethanolamine) acted as catalyst with H 2 O 2 and HNO 3 in Cy oxidation [18].…”
