The cyclopropanation of the enoxysilane by the ultrasound- accelerated Simmons-Smith reaction was studied intensively. Experimental results reveal that ultrasound and copper(Ⅰ) chloride can efficiently activate the zinc dust, and result in 56~78% yields of cyclopropane products. Then, the effects of the intensity of ultrasonic waves, the temperature, the solvent and the reaction time were examined.
