摘要：
The reactivity of the imido-Mo(IV) species [(5-Cp)(2)Mo((NBu)-Bu-t)], 1, towards the iodine-based oxidant PhIO was investigated and yielded the m-oxodimolybdenum(V) dimer [{(eta(5)-Cp)(eta(1)-Cp)Mo((NBu)-Bu-t)}(2)O], 2. X-Ray crystallography and H-1-NMR of 2 indicate slipping of one of the eta(5)-Cp ring on each Mo center to eta(1)-Cp as the result of the coordination of the oxygen atom. DFT investigation of the OAT reaction to complex 1 revealed a transient Mo(IV)-oxo species as the most likely intermediate.
