5-Iodo-l,2,3-triazolium-based multidentate halogen-bond donors as activating reagents

摘要

Bi- and tridentate polycationic halogen bond donors based on 5-iodo-l,2,3-triazolium groups have been synthesized by 1,3-dipolar cycloaddition reactions. These halogen-based Lewis acids have been evaluated as activators in a halide-abstraction benchmark reaction.
