[摘要]:Halofluorination of alkenes with a new system (trihaloisocyanuric acids and HF center dot pyridine) results in the formation of vicinal halofluoroalkanes. The reaction is regioselective leading to Markovnikov-oriented products and the halofluorinated adducts follow anti-addition in the case of cyclohexene and 1-methylcyclohexene. Reaction yields range from 67-88%. |
