2-Nitro-2-phenylthio oxiranes (3), prepared by nucleophilic epoxidation of 1-nitro-1-phenylthio alkenes (1), react with a variety of heteroatomic nucleophiles to give α-substituted S-phenylthio esters (2). Of special note is the efficient reaction of 2-nitro-2-phenylthio oxiranes with boron trifluoride etherate in toluene at room temperature to give α-fluoro S-phenylthio esters (8).
通过1-硝基-1-苯基硫代烯烃的亲核环氧化反应制得的2-硝基-2-苯基硫代肟基(3)(1)与多种杂原子亲核试剂反应,得到α-取代的S-苯基硫代酸酯(2)。特别值得注意的是,在室温下,2-硝基-2-苯基硫代肟酮与三氟化硼醚化物在甲苯中的有效反应可生成α-氟S-苯基硫代酸酯(8)。
