Beckmann rearrangement of ketoxime catalyzed by acidic ionic liquid-N-methyl-imidazolium hydrosulfate was studied. Rearrangement of benzophenone oxime gave the desirable product with 45% yield at 90 ?C. When co-catalyst P2O5 was added, the yield could be improved to 91%. The catalyst could be reused three cycles with the same efficiency. Finally, reactions of other ketoximes were also investigated.

A [bmIm]OH-catalyzed amidation of azides and aldehydes is reported. This reaction is easily handled and proceeds under mild conditions. The overall transformation involves azide-enolate cycloaddition, which subsequently undergoes rearrangement to give amides. Importantly, the employment of ionic liquid makes this transformation green and practical.

A convenient protocol for the C-N cross-coupling of aliphatic amides and iodobenzene is demonstrated using a simple and inexpensive Co(C2O4)·2H2O/N,N′-dimethylethylenediamine (DMEDA) catalytic system in water. Good yields of N-arylated products were isolated (up to 85%) and the protocol has been successfully applied to the synthesis of the anticancer drug, flutamide.
