A mild and efficient catalyst for the Beckmann rearrangement, BOP-Cl
摘要:
BOP-Cl (bis(2-oxo-3-oxazolidinyl)phosphinic chloride) was found to be very active as the first organophosphorus catalyst (1-5 mol % loading) for the Beckmann rearrangement of various ketoximes to the corresponding amides in anhydrous acetonitrile at refluxing temperature.

organocatalytic Beckmannrearrangement of ketoximes into amides has been realized by the catalytic use of cyanuric chloride. Furthermore, acids such as HCl and ZnCl2 are effective as cocatalysts with cyanuric chloride. For example, azacyclotridecan-2-one, which is synthetically useful as a starting material for nylon-12, was prepared in quantitative yield by the Beckmannrearrangement of cyclododecanone
