摘要

Novel moon(dithiolato) molybdenum(VI) and tungsten(VI) complexes were isolated through the searching for potential active species in the catalytic air oxidation of benzoin by [Mo ~vO(SR)_4]~- complexes. Among these, (NEt_4)_2 [{Mo ~(VI)O_2(3-triphenylsilyl-1,2-benzenedithiolato)}_2(#mu#-O)] centre dot 2DMF (1), (PPh_4)_2 [{W~(VI)O_2(1,2-benzenedithiolato)}_2(#mu#-O)] (3), and (NEt_4)_2 [{W~(VI)O_2(2,3-naphthalenedithiolato)}_2(#mu#-O)] (5) were structurally characterized by X-ray crystallography. The electro chemical, electronic, as well as Raman/IR spectral properties of the tungsten complexes, 3 and 5, have been investigated and compared with the corresponding bis(dithiolato) complexes, e.g. [W~(VI)O_2(dithiolato)_2]~(2-). The #mu#-oxo-binuclear species, [{Mo~(VI)O_2(SR)_2}_2(#mu#-O)]~(2-), is proposed as a possible active species for the catalytic air oxidation of benzoin by the Mo(V) thiolato complexes.
