l-3-acyloxy-2-pentene (4), the yields changing with base, solvent, phase-transfer catalyst, and their combination. In the presence of triethylamine, fluorination occurs exclusively, producing acid fluorides in good yields. Alcohols and 2-pyridone are converted into alkyl fluorides and 2-fluoropyridine, respectively, with use of triethylamine as a base with an aprotic solvent. The reactions of PMP with
