The oxidative fluorination of pyridine and 4-ethylpyridine under chemical and electro-chemical conditions in the presence of transition metal (high-oxidation-state nickel, cobalt, and silver) salts was studied. The chemical fluorination affords 2-fluoropyridine in all cases, while the electrochemical fluorination results in 2-fluoroor 3-fluoropyridine depending on the catalyst used.
研究了在过渡金属(高氧化态镍、钴和银)盐存在下,在化学和电化学条件下吡啶和 4-乙基吡啶的氧化氟化。在所有情况下,化学氟化产生 2-氟吡啶,而电化学氟化产生 2-氟或 3-氟吡啶,具体取决于所用的催化剂。
