超声辐射下一锅法制备O-芳磺酰基芳醛肟
One-Pot Synthesis of O-Arylsulfonyl Arylaldoximes under Ultrasound Irradiation
【摘要】 在超声辐射和NaOH存在下,由芳醛肟与芳基磺酰氯在室温CH2Cl2中反应15~60 min生成相应的O-芳磺酰基芳醛肟,收率56%~94%.操作简便,反应条件温和,时间短,产率高.
【Abstract】 One-pot synthesis of O-arylsulfonyl arylaldoximes was carried out in 56%~94% yields via the condensation of arylaldoxime with aromatic sulfonyl chloride in the presence of sodium hydroxide at room temperature in dichloromethane under ultrasound irradiation. The advantages of this methodology are convenient operation, mild conditions, short reaction times, and high yields.
