Bromodimethylsulfonium Bromide-ZnCl2: A Mild and Efficient Catalytic System for Beckmann Rearrangement

[摘要]：Bromodimethylsulfonium bromide, in combination with zinc chloride, has been shown to be an excellent catalytic system for liquid-phase Beckmann rearrangement of various ketoximes into the corresponding amides/lactams in acetonitrile at reflux temperature with good to excellent yields.
