abstract |
The dinuclear complex [Mo2O6(di-tBu-bipy)(2)] (1) (di-tBu-bipy = 4,4'-di-tert-butyl-2,2'-bipyridine) was obtained as a minor product of the hydrothermal reaction of MoO3 and di-tBu-bipy, and structurally characterized by single-crystal X-ray diffraction. In the molecular structure of 1 two distorted MoO6 octahedra share a common edge to form a dioxo-bridged Mo2O6 unit which is coordinated by di-tBu-bipy ligands. The catalytic performance of 1 for the epoxidation of non-functionalized olefins using tert-butylhydroperoxide as oxidant compares favorably with that reported for other oxomolybdenum(VI) complexes bearing the same organic ligand. The catalyst exhibits regioselectivity toward internal olefin epoxidation over external olefin epoxidation. (C) 2012 Elsevier B.V. All rights reserved. |
