“…However, validation of this hypothesis would require more detailed studies, e.g., computational chemistry. [35,39,[41][42][43][44][45][72][73][74][75][76]. The neutral complex [MoO(O2)2(2,2′-bipy)] led to 28% conversion at 24 h/70 °C, in water (entry 23) [35].…”

“…Neutral Mimoun type mononuclear complexes are well established catalysts for olefin epoxidation, as highlighted in several reviews [6,7,[26][27][28][29]. These catalytic systems may use eco-friendly oxidants such as hydrogen peroxide [3,4,[30][31][32][33][34][35][36][37][38] and tert-butyl hydroperoxide (TBHP) [8,30,35,[39][40][41][42][43][44][45], and different types of solvents: catalyst/H 2 O 2 systems with organic solvents [3,4,[30][31][32][33][34], water [35], ionic liquids [36,37,46] or without solvent [38]; and catalyst/TBHP systems with an organic solvent [8,30,[39][40][41][47][48][49][50]…”

Ionic oxidoperoxido-molybdenum(VI) complexes of the type [Cat][MoO(O2)2(pic)], with pic = N,O-chelated picolinate ligand and Cat = monocation, were prepared in high yields (82–95%) from the precursor complex [H3O][MoO(O2)2(pic)] via [H]+ cation exchange for 1-ethyl-3-methylimidazolium [EMIM]+, 1-butyl-3-methylimidazolium [BMIM]+, 1-octyl-3-methylimidazolium [OMIM]+, N-cetylpyridinium [C16Py]+, and N-methyl-N,N,N-trioctylammonium [Aliquat]+. The structure and purity of the ionic compounds were assessed by 1H and 13C NMR, FT-IR, and elemental analysis (C, H, N), and the electrochemical properties were studied by differential pulse voltammetry (DPV) and cyclic voltammetry (CV). The [Cat][MoO(O2)2(pic)] compounds showed promising catalytic epoxidation activity based on the model reaction of cis-cyclooctene with tert-butyl hydroperoxide as oxidant. The type of cation influenced the physical state of the compound and the catalytic performance.

Molybdenum complexes are versatile and efficient for liquid phase olefin epoxidation reactions. Rational design of catalysts is critical to achieve high atom efficiency during epoxidation processes. Although liquid phase epoxidation has been a popular topic for decades, three key issues, (a) rational control of morphology of molybdenum nanoparticles, (b) manipulating metal‐support interaction and (c) altering electronic configuration at molybdenum center remains unsolved in this area. Therefore, in this paper, we have critically revised recent research progress on heterogeneous molybdenum catalysts for facile liquid phase olefin epoxidation in terms of catalyst synthesis, surface characterization, catalytic performance and structure‐function relationship. Furthermore, plausible reaction mechanisms will be systematically discussed with the aim to provide insights into fundamental understanding on novel epoxidation chemistry.

Cu- and Ni-Grafted Functionalized Mesoporous Silica as Active Catalyst for Olefin Oxidation

et al. 2017

View full text Add to dashboard Cite

Mesoporous silica has been functionalized with 3‐aminopropyl triethoxy silane (3‐APTES), followed by Schiff‐base condensation with 2‐hydroxy‐1‐naphthaldehyde. Incorporation of copper and nickel by covalent grafting onto the Schiff‐base loaded materials gives two heterogenized catalysts namely, Cu–Cat and Ni‐Cat, respectively. The materials have been characterized by PXRD analyses, nitrogen sorption studies, TEM, TGA, FT‐IR, UV‐visible and solid state MAS‐NMR spectroscopy. The metal‐contents in the samples are estimated using ICP‐AES studies. Cu–Cat and Ni‐Cat have been used as active catalyst in the oxidation of various olefins e. g. styrene, α‐methyl styrene, cyclohexene, trans stilbene and cyclooctene in the presence of tert‐butyl hydroperoxide as the oxidant in acetonitrile under mild conditions. Different products have been analyzed by gas chromatography and gas chromatography‐mass spectrometry. The results show high conversion of the substrates, moderate to good product selectivity and high TOFs of the reactions. The catalysts are recycled without deteriorating their activities and heterogeneous nature.
