phenylsulphenyl chloride at room temperature to furnish α-chloro-α-(phenylthio)cycloalkanones which undergo ready dehydrochlorination to α-(phenylthio)cycloalkenones when treated with triethylamine; acyclic, terminal α-diazoketones also furnish α-chloro-α-(phenylthio)adducts which are useful electrophiles in the synthesis of α-phenyl-α-(phenylthio)ketones.
在室温下,环状α-二氮酮与苯磺酰氯反应生成α-氯-α-(苯硫基)环链烷酮,当用三乙胺处理时,α-氯代-α-(苯硫基)环烯酮易于脱氯化氢成α-(苯硫基)环烯酮。无环末端α-二氮酮还提供α-氯代-α-(苯硫基)加合物,它们在合成α-苯基-α-(苯硫基)酮中是有用的亲电子试剂。
