ChemInform Abstract: Reactivity of Cationic Molybdenum(II) Complexes. Part 3. Synthesis of Methoxide and Carbomethoxide Derivatives of η‐Pentamethylcyclopentadienyl‐Molybdenum(II) and the Crystal Structure Determination of the Oxidation Product trans‐((Mo(η‐C5Me5)(O)2)2(μ‐O)).

Abstract The reaction of the complex (I) with NaOMe gives a mixture of cis‐(III) and trans‐(IV), which decarbonylates in various solvents yielding a mixture of (V) and (VI).
