The reactions of four highly-toxic fluorobutenes – perfluoroisobutene (PFIB), 1-hydropentafluorocyclobutene (1-H), hexafluorocyclobutene (HFCB) and 3-chloropentafluorocyclobutene (3-Cl)—with propanethiol, 2,6-dimethoxybenzenethiol and N-acetylcysteine isopropyl ester were studied. PFIB and HFCB reacted with two molar equivalents of the aliphatic thiols, but with only one molar equivalent of the aromatic
四种剧毒的氟丁烯–全氟异丁烯(PFIB),1-氢五氟环丁烯(1-H),六氟环丁烯(HFCB)和3-氯五氟环丁烯(3-Cl)与丙烷硫醇,2,6-二甲氧基苯硫醇和N的反应研究了乙酰乙酰半胱氨酸异丙酯。PFIB和HFCB与2摩尔当量的脂族硫醇反应,但仅与1摩尔当量的芳族硫醇反应(推测是由于位阻),在反应活性上类似于光气。氟环丁烯1-H和3-Cl分别与一摩尔当量和至多三摩尔当量的脂族硫醇反应,但仅与一摩尔当量的芳族硫醇反应。分离出烯丙基和乙烯基取代的产物,并尽可能充分地表征。氟环丁烯对啮齿类动物的吸入毒性与易取代的氟取代基的数量有关,这支持了毒性是由于与肺中生物硫醇反应而引起的争论。
