Abstract
Microwave irradiation하에서 황산 실리카를 사용한 케톤에서 아미드의 합성을 관한 one-pot Beckmann자리옮김 반응에 대한 보고이다. 산과 케톤의 몰비율이 1:2인 이 방법의 장점은 간단한 조작과 짧은 반응시간으로 높은 수율을 가진 위치선택적 반응이고, 최근에 사용되었던 방법보다 더 친환경적이다.

A one-pot Beckmann rearrangement for the preparation of amides from ketones is described using the silica sulfuric acid under Microwave irradiation. Advantages of this method are regioselectivity with high yields in a simple operation and short reaction time, in which the mole ratio of acid and ketone was 1:2 and it should be greener than the currently used systems.
