Ultrasonic assisted synthesis of gem-dichloroaziridine derivatives using Mg/CCl4 under neutral conditions

• Ultrasonic irradiation catalyzed synthesis of gem-dichloroaziridines.
• Any phase transfer catalyst was needed for this reaction under ultrasonic condition.
• Products were obtained in excellent yields and short reaction times.
• Simplicity of the method and high purity of products.
• Neutral condition and simple work up.

A novel and convenient method for synthesis of gem-dichloroaziridine derivatives was reported in that was utilized Mg powder with CCl4 for dichlorocarbene generation under ultrasonic irradiation. In this clean and efficient reaction procedure, the desired products were purely obtained in excellent yields. The other advantages of this method are availability of reagents, very short reaction times, simplicity of the method, easily work up, neutral reaction medium and high purity of products.
