A new method for preparation of nitrile oxide compounds in solvent free condition from oximes

Synthesis of oximes is an important reaction in organic chemistry. The reaction of oximeswith NCS (N-Choloro soccyinimide) in nitrogen inert condition and presence ofthreeethylamine and basic ionic liquids led to crystalline intermediate. This compound washeating and nitrile oxide compounds prepared in high yield. Nitrile oxide reacted witholephins and synthesis iso oxazole heterocycles
