Metal–free Efficient Method for the Synthesis of N‐(2‐haloethyl)benzamides through the Ring‐opening of2‐oxazolines
View through CrossRef
Abstract
An efficient, metal‐free C–H halogenated method for the synthesis of β‐halogenated carboxamides using non‐corrosive NXS (X=Cl, Br) as the halogenated source and ammonium sulfocyanide (NH

SCN) as the additive was proposed and accomplished. Various substituted 2‐oxazolines efficiently afforded the corresponding β‐halogenated carboxamides via a ring‐opening reaction in good yields. The characteristic features of this reaction include readily available materials, mild reaction conditions and functional groups tolerance.
