Synthesis and Catalytic Properties in Olefin Epoxidation of Octahedral Dichloridodioxidomolybdenum(VI) Complexes BearingN,N-Dialkylamide Ligands: Crystal Structure of [Mo2O4(μ2-O)Cl2(dmf)4]

Molybdenum complexes with a μ-O{MoO2}2 core: their synthesis, crystal structure and application as catalysts for the oxidation of bicyclic alcohols using N-based additives

Binuclear molybdenum(vi) complexes with a μ-O{MoO₂}₂ core as catalysts for the oxidation of bicyclic alcohols (fenchyl alcohol and isoborneol), using 30% H₂O₂ as the oxidant in the presence of NEt₃ as the additive, are reported.

Dichlorodioxomolybdenum(vi) complexes bearing oxygen-donor ligands as olefin epoxidation catalysts

The complexes [MoO₂Cl₂(N,N-dimethylbenzamide)₂] and [MoO₂Cl₂(N,N′-diethyloxamide)] are active olefin epoxidation catalysts and can be easily recycled when using ionic liquid solvents.

μ-Oxido-bis-[chlorido(4,4'-di-tert-butyl-2,2'-bipyridine-κN,N')dioxido-molybdenum(VI)] 0.2-hydrate

The title hydrate, [Mo(2)Cl(2)O(5)(C(18)H(24)N(2))(2)]·0.2H(2)O, has been isolated as the oxidation product of [Mo(η(3)-C(3)H(5))Cl(CO)(2)(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A μ-oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O(2) units, having the terminal oxide ligands mutually cis, and the chloride and μ-oxide trans to each other. In the binuclear complex, the coordination geometries of the metal atoms can be described as highly distorted octa-hedra. Individual complexes co-crystallize with a partially occupied water mol-ecule of crystallization (occupancy factor = 0.20; H atoms not located), with the crystal packing being mediated by the need to effectively fill the available space. A number of weak C-H⋯O and C-H⋯Cl inter-actions are present.
