The mer-octahedral complexes(2-carbonyl)(4-Me)(6-tBu)-phenolato[C,O] hydridotris(trimethylphosphine)cobalt(III) (1) or (1-carbonyl)(2-oxo)(1,2- diphenylethene)[C,O]hydridotris(trimethylphosphine)cobalt(III) (2) via formal insertion of propynoic acid ethyl ester into Co-H functions afford pentacoordinate vinylcobalt(III) 3 and 4, respectively, that are diamagnetic and attain a square pyramidal structure as exemplified by an X-ray diffraction analysis of 3.
