Metal-free C–N cross-coupling of electrophilic compounds and N-haloimides†
Abstract
When DBU is added, the cross-coupling reaction between alkyl halides (halogen = Cl, Br and I) and N-haloimides (halogen = Cl, Br) occurs, resulting in the formation of aminated products. A halogen bond activated nucleophilic substitution mechanism was proposed. The methodology represents an elegant example of applying the halogen bond activation strategy in an organic transformation.
