摘要：

Methyl(oxo)bis(eta(2)-peroxo)rhenium(VII) 1, the active species of the system CH3ReO3/H2O2 in the catalytic oxidation of different organic and organometallic compounds, is stabilized by a water molecule attached to the rhenium center. This water molecule can be removed and substituted by hexamethylphosphoramide (HMPA) to yield (hexamethylphosphoramide)methyl(oxo)bis(eta(2)-peroxo)rhenium(VII) (3). The synthesis, crystal structure (X-ray diffraction study), and catalytic properties of which compound are reported. Crystal data are as follows: monoclinic, space group P2(1)/n, a = 900.76(7) pm, b = 1229.80(11) pm, c = 1318.57(11) pm, beta = 90.251(7)degrees, R(w) = 0.034 for 1878 reflections. The catalytic properties of compound 3 in the oxidation of olefins with H2O2 are similar to those of 1.
