Direct Observation by Electrospray Ionization Mass Spectrometry of
The use of methanol as solvent is essential for the formation of the double-bookshelf-type oxide cluster [(Cp*Rh)(2)Mo(6)O(20)(OMe)(2)](2-) from [{Cp*Rh(µ-Cl)Cl}(2)] and four equivalents of [Mo(2)O(7)](2-). The reaction proceeds via [Cp*RhMo(3)O(8)(OMe)(5)](-). The proposed structure for this key intermediate (shown schematically) is supported by electrospray ionization mass spectrometry and labeling experiments with CD(3)OD as solvent. Cp*=eta(5)-C(5)Me(5).
