摘要

The cobalt (III) dimethyl halide complexes cis, mer-(PMe3) 3Co (CH3) 2X (X= Cl, I) were found to undergo a degenerate cobalt-to-cobalt transfer of the methyl ligands during isotopic labeling experiments. Extensive mechanistic studies exclude radical, methyl iodide elimination, and disproportionation/comproportionation pathways for exchange of the methyl groups between metals. A related cobalt (III) dimethyl complex supported by the tridentate ...
