摘要:

研究了卤代烃在光促进温和条件(常温常压)非贵金属[Co(acac)2,Co(OAc)2或CoCl2]催化下与二氧化碳的羰基化反应;同时对反应过程中的ESR谱进行了研究. ESR谱研究表明,在光促进下二氧化碳参与的羰基化反应中有二氧化碳游离基负离子(CO·-2)[用DMPO(5,5-二甲基-1-吡咯啉-N-氧化物)捕获]生成.

关键词: ESR谱, 二氧化碳, 光促进, 羰基化反应

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
