Abstract:

Photopromoted carbonylation of alkyl halides with carbon dioxide was carried out under ambient conditions using non-precious transition metals catalysts such as [Co(acac)2, Co(OAc)2 or CoCl2]. The ESR method was used to study of the reaction. ESR spectroscopic measurements using DMPO (5,5-dimethyl-1-pyrroline N-oxide) as a spin trapping agent confirmed the formation of carbon dioxide anion radicals (CO·-2) in the photopromoted carbonylation of carbon dioxide.

Key words: ESR spectroscopy, carbon dioxide, light promotion,  carbonylation
