Der austausch des cyclopentadienylliganden im methylcyclopentadienyl-mangantricarbonyl

Abstract The exchange of the cyclopentadienyl ring in methylcyclopentadienylmanganese(I) tricarbonyl by methy-substituted benzenes in the presence of aluminium halide leads to [arene-Mn(CO) 3 ] + -ions. The reaction conditions have been optimised; in addition to the yield the purity of the complexes has been determined in some detail. After mild decomposition the arenes were analysed by GLC. Pure [arene-Mn(CO) 3 ] + -ions can be isolated with benzene, toluene, m - and o -xylene.
