Formation of organocobalt porphyrin complexes by reactions of cobalt(II) porphyrins with azoisobutyronitrile and organic substrates

Abstract

Reaction of a cobalt(II) porphyrin with azoisobutyronitrile (AIBN) at 333 K provides a convenient source of a transient cobalt hydride that reacts with alkenes and alkynes to form secondary alkyl and vinyl complexes, respectively or alternatively with organic halides and epoxides in the presence of donor molecules to form primary alkyl and β-hydroxyalkyl complexes.
