Autor: Salvatore D. Lepore, Anjan K. Bhunia, Deboprosad Mondal, Shuiyu Lu, Pamela C. Cohn, Song Ye Li, Victor W. Pike

Publikováno v: The Journal of Organic Chemistry. 74:5290-5296

A series of arylsulfonate nucleophile assisting leaving groups (NALGs) were prepared in which the metal chelating unit is attached to the aryl ring via an ether linker. These NALGs exhibited significant rate enhancements in halogenation reactions usi
