Perfluoro-2-methylpent-2-en-3-yl isothiocyanate reacts with ethyl or isopropyl alcohols in the presence of NEt3 to give derivatives of 4,5-dihydrothiazole and ethoxy(ethylthio)methylene-(1,1,1,4,4,5,5,5-octafluoro-2-trifluoromethylpent-2-en-3-yl)amine and isopropoxy(isopropylthio)methylene-(1,1,1,4,4,5,5,5-octafluoro-2-trifluoromethylpent-2-en-3-yl)amine, respectively. Heating of ethyl or isopropy
全氟-2-甲基戊-2-烯-3-基异硫氰酸酯在 NEt3 存在下与乙醇或异丙醇反应生成 4,5-二氢噻唑和乙氧基(乙硫基)亚甲基-(1,1,1,4, 4,5,5,5-octafluoro-2-trifluoromethylpent-2-en-3-yl)amine and isopropoxy(isopropylthio)methylene-(1,1,1,4,4,5,5,5-octafluoro-2) -三氟甲基戊-2-烯-3-基)胺,分别。乙基或异丙基 N-(全氟-2-甲基-2H-戊基-3-氨基)硫代氨基甲酸酯与碳酸钾在 DMF 中加热产生相同的产物加上 3-四氟亚乙基-5,5-双(三氟甲基)噻唑烷-2-酮。后者的结构由X射线衍射分析证实。该化合物在溶液 (CCl4) 和固态 (KBr) 中的红外光谱数据表明分子间 NH 的形成...
