Monofluorination of α-dichlorosulfides: A short access to α-fluoro polyfunctionalised thioethers
摘要:
alpha-Chlorinated-alpha-fluorinated thioethers were synthesized in good yields by nucleophilic fluorination of their corresponding dichlorinated thioethers. A complete conversion of dihalosulfides 2 into alpha-fluoro-alpha-chlorosulfides 3 was achieved with Et3N.3HF in refluxing acetonitrile. (C) 1997 Elsevier Science Ltd.
