In the system Me4Pb/Me3Pb[M(CO)5]/Me2Pb[M( CO)5]2 (Me = CH3; M = Mn, Re) redistribution can occur. The single reactions involved, disproportionation of Me3Pb[M(CO)5] (M = Mn, Re) and conproportionation of Me4Pb and Me2Pb[Mn(CO)5]2 to Me3Pb[Mn(CO)5]2 have been investigated kinetically by 1H NMR spectroscopy in various solvents, and initial phase rate constants have been determined. Both types of reactions proceed according to a 2nd order rate law. Conproportionation is faster than Re compounds. The solvent dependency of the reaction can be explained when a reaction mechanism via a bridged transition state is assumed.
