Electrolytic reactions of fluoro organic compounds. 9. Fluoride ion promoted anodic substitutions of chalcogeno compounds. 1. Regioselective anodic alkoxylation of sulfides
摘要:
Anodic alpha-alkoxylation of sulfides was remarkably promoted in the presence of fluoride ions: When Et3N.3HF was used as a supporting electrolyte, simple alkyl phenyl sulfides and sulfides bearing weak electron-withdrawing groups underwent anodic alkoxylation via fluorosulfonium ions as key intermediates in a unique Pummerer-type mechanism with reasonable or high yields for the first time.
