The Beckmann rearrangement of a variety of ketoximes has been carried out in imidazolium based ionic liquids in the presence of catalytic amounts of 2,4,6-trichloro [1,3,5] triazine. This mild and green procedure is highly regioselective affording the corresponding N-substituted amides in very good to quantitative yields.

Beckmann rearrangement of oximes catalyzed by cyanuric chloride in ionic liquids
2008
Abstract
The Beckmann rearrangement of a variety of ketoximes has been carried out in imidazolium based ionic liquids in the presence of catalytic amounts of 2,4,6-trichloro [1,3,5] triazine. This mild and green procedure is highly regioselective affording the corresponding N-substituted amides in very good to quantitative yields. The ionic liquids were easily recovered and recycled several times.File in questo prodotto:
