An alkylcobalt(I) intermediate in the formation of trans-dialkylcobalt(III) complexes of two tetradentate macrocyclic ligands
Abstract
The vitamin B12 model compounds trans-[RCo(tim)X]Y and trans-[RCo(cr)X]Y can be reduced to neutral alkylcobalt(I) complexes of a new type, which are readily oxidatively alkylated at the cobalt atom to yield trans-dialkylcobalt(III) derivatives.
