摘　　要：Photopromoted carbonylation of bromohydrocarbon catalyzed by cobalt complexes can be carried out under ambient conditions in CH3OH/DMF.It is found that DMF can be decomposed into CO under irradiation and thus can be used as a CO source for the photopromoted carbonylationof bromohydrocarbon,which has been proved by isotope experiment of H13CON（CH3）2.In this paper,the effect of different cobalt catalysts on photopromoted carbonylation of bromohydrocarbon is studied and the way which photopromoted carbonylation of bromohydrocarbon proceed through is deduced.Photopromoted carbenylation of bromohydrocarbon catalyzed by cobalt complexes can be carried out under ambient conditions in CH3OH/DMF. It is found that DMF can be decomposed into CO under irradiation and thus can be used as a CO source for the photopromoted carbonylationof bromohydrocarbon, which has been proved by isotope experiment of H^13 CON（ CH3 ）2. In this paper,the effect of different cobalt catalysts on photopromoted carbonylation of bromohydrocarben is studied and the way which photopromoted carbonylation of bromohydrocarben proceed through is deduced.
