Cobalt silyl complexes reductive elimination

Brookhart s group has discovered a new hydrido organocobalt complex in which the cobalt atom is in a high oxidation state. They thus reported a rare example of an organometallic cobalt derivative with a +v formal oxidation state for the cobalt center 10. This species contained additional silyl ligands that stabilized such high oxidation state complexes. These species were remarkably resistant toward reductive elimination. The 2.28 A H-H and the...
