The possibility synthesizing compounds of the type (η 5 −C 5 H 5 )M(CO) 3 M′Cl (M = Mo, W; M′ = Mg, Zn, Cd) by direct metal interaction with chlorides of cyclopentadienyltricarbonylmolybdenum and tungsten was demonstrated. In the case of magnesium derivatives of the type [(η 5 −C 5 H 5 )M(CO) 3 ] 2 Mg were observed also. The kinetics of magnesium, zinc and cadmium oxidation by Ph 3 SnCl, (η 5 −C 5 H 5 )Mo(CO) 3 Cl and (η 5 −C 5 H 5 )W(CO) 3 Cl in tetrahydrofuran and N,N ‐dimethylformamide was investigated. Rate constants and activation energy were determined. For the process of oxidation a Langmuir–Hinshelwood scheme was proposed. The kinetic data obtained make it possible to calculate the equilibrium constants, enthalpy and entropy of adsorption of the oxidant and coordinating solvent on metal surface.
