摘要：

Aminochlorination of methylenecyclopropanes (MCPs) 1 can be achieved under CO2 atmosphere using N,N-dichlorotoluenesulfonamine (TsNCl2) as the nitrogen and halogen sources at room temperature to give the corresponding normal ring-remaining aminochlorinated products 2 along with/without the ring-opened aminochlorinated products 3 in moderate to good total yields. The present process takes the advantage of the green benign reaction conditions in the absence of any metal catalyst and solvent.
