Beckmann Rearrangement of Ketoximes to Lactams by Triphosphazene Catalyst

Triphosphazene, 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-chloride (TAPC), was found to be an efficient catalyst for the Beckmann rearrangement of cyclohexanone oxime and cyclododecanone oxime to ε-caprolactam and laurolactam, which are raw materials of nylon-6 and nylon-12, respectively.
