“…This study not only contributes to the understanding of manganese-based catalysis but also highlights the potential utility of these manganese complexes, specically 4 0 -Ar 2,2 0 :6 0 ,2 00 -TPY ligated manganese(II) complexes, in the development of efficient and selective catalytic systems for olen oxidation and cycloaddition reactions, with a particular emphasis on their application in the oxidation of styrene using tert-butylhydroperoxide as an oxidant. 64 The results revealed that the products of cyclohexene 114 were 2-cyclohexene-1-one 115, 2-cyclohexene-1-ol 116, and cyclohexene epoxide 117. 64 Effects of different Mn(II) for conversion of cyclohexene oxidation are shown in Table 6.…”

Two new homobinuclear manganese compounds with mixed ligands, [Mn2(μ1,1–2‐NH2C6H4COO)2(phen)4](ClO4)2(CH3OH) (1), and [Mn2(μ1,3–2‐NH2C6H4COO)2(bipy)4](ClO4)2 (2) (NH2C6H4COOH = anthranilic acid, bipy = 2,2′‐bipyridine, phen = 1,10‐ phenanthroline) were synthesized and thoroughly characterized by elemental analysis, IR, UV and single crystal X‐ray crystallography. X‐ray structure analysis shows that in the mono‐ and bidentate carboxylate bridged compounds, Mn–Mn distances of 1 and 2 are 3,461 Å, and 4,639 Å, respectively. The energy of the compounds was determined with a DFT (Density Functional Theory) calculation on B3LYP/6‐31G(d,p) optimized geometry by using the B3LYP/6‐31G(d,p) basis set. These compounds acts as biomimetic catalyst and show catalase‐like activity for the hydrogen peroxide dismutation at room temperature in different solvents with remarkable activity (TOF, Turnover frequency = mol of subst./(mol of cat. × time)) up to 12640 h−1 with 1, and 17910 h−1 with 2 in Tris–HCl buffer). Moreover, the catalytic activity of 1 and 2 has been studied for oxidation of alcohols (cinnamyl alcohol, benzyl alcohol, cyclohexanol, 1‐octanol and 1‐heptanol) and alkenes (cyclohexene, styrene, ethyl benzene, 1‐octene and 1‐hexene) in a homogeneous catalytic system consisting t‐butylhydroperoxide (TBHP) as an oxidant in acetonitrile. Both compounds exhibited very high activity in the oxidation of cyclohexene to cyclohexanone (~80% selectivity, ~99% conversion in 1 h, TOF = 243 h−1 and 226 h−1) and cinnamyl alcohol to cinnamaldehyde (~64% selectivity) as the main product with very high TOF value (9180 h−1 and 13040 h−1 in the first minute of reaction) (~100% conversion in 0.5 h) with TBHP at 70 °C in acetonitrile, for 1 and 2, respectively.

2,2′:6′,2′′‐Terpyridine (tpy) and its derivatives represent highly versatile ligands for the complexation of transition metal ions. Today, such complexes are employed in a highly diverse fashion – including inter alia materials science, opto‐electronics, pharmacy or catalysis. Concerning the latter one, a vast development has led to new or improved applications in both “conventional” organic chemistry (i. e., catalysis of functional‐group interconversions, CH‐activation or cross‐coupling reactions) as well as energy‐related applications (e. g., CO2 reduction, artificial photosynthesis, dye degradation). In this respect, not only homogeneous catalysts (i. e., molecular complexes) but also heterogeneous and recyclable ones have moved to the focus of interest. These heterogeneous structures include 1D metallopolymers, metal‐organic frameworks (MOFs), organic‐inorganic hybrids and bio‐inspired catalysts. We gave a first overview on this topic already in 2011; in here, the methods and implementations established within the last decade as well as relevant contributions from earlier works are presented and discussed.
