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 correspon...
A series of 2,4-dibromobutenes were synthesized by the reaction of methylenecyclopropanes with KBr in HOAc in the presence of dibenzoyl peroxide, providing an environment friendly method for the synthesis of 2,4-dibro...
