  摘要：

  Tetramethyloxoosmium(VI) (2a), the first example of methylosmium oxides (CH3)(x)Os(y)O(z), has been synthesized from osmium tetraoxide (1a) and dimethylzinc (19% yield) or methyltris(isopropoxy)titanium (50% yield). A more directed synthesis (60% yield) is methylation of the glycolate osmium(VI) complex O = activated Os(OCH2CH2O)2 (1b), which precursor compound is in turn accessible from 1a in quantitative yield. The thermally labile ethyl derivative tetraethyloxoosmium(VI) (2b), the first well-characterized example of its class (C2H5)(x)Os(y)O(z), is also reported. The title compound 2a is an orange, air-stable, volatile, crystalline compound that melts at 74-degrees-C without decomposition. The gas-phase average molecular structure of 2a, as determined by electron diffraction techniques, is consistent with a theoretical model having C4 symmetry, with the most important parameters being r(a)(Os-C) = 209.6 (3) pm, r(a) (Os = O) = 168.1 (4) pm, and angle (OOsC) = 112.2 (5)-degrees. According to PE spectroscopic data, the d ionization of 2a occurs at 8.55 eV. The title compound 2a undergoes irreversible oxidation at +2.2 V, reversible reduction at-1.58 V (cyclic voltammetry).
