Claims (6)
- 하기 일반식(I)의 할로겐 화합물과 하기 일반식(II)의 케톤을 알칼리성 축합제 및 촉매의 존재하에 축합시켜 불포화 케톤을 제조하는 방법에 있어서, 동일 반응계에서 트리에틸아민과 요오드화 나트륨을 반응시켜 촉매를 공급함을 특징으로 하는, 신규한 불포화 케톤 제조방법.상기식에서, X는 할로겐원자를 나타내고, R 및 R'는 각각 독립적으로 수소원자 또는 C1-5알킬이거나, R 및 R'이 함께 -(CR1R2)n-(이때, R1및 R2는 각각 독립적으로 수소원자 또는 C1-5알킬기이며, n은 1 내지 3의 정수이다)의 알킬렌으로서 잔기와 함께 고리구조를 형성할 수 있다.
- 제 1 항에 있어서, 상기 일반식(I)의 할로겐 화합물이 프레닐 클로라이드 또는 프레닐 브로마이드인 방법.
- 제 1 항 또는 제 2 항에 있어서, 상기 일반식(II)의 케톤이 아세톤인 방법.
- 제 1 항에 있어서, 상기 일반식(I)의 화합물 1몰에 대해 상기 트리에틸아민을 0.01몰 내지 0.005몰의 양으로 사용하고, 상기 요오드화 나트륨을 0.005몰 내지 0.03몰의 양으로 사용하는 방법.
- 제 4 항에 있어서, 상기 일반식(I)의 화합물 1몰에 대해 상기 트리에틸아민을 0.01몰 내지 0.03몰의 양으로 사용하고, 상기 요오드화 나트륨을 0.005몰 내지 0.01몰의 양으로 사용하는 방법.
- 제 1 항에 있어서, 상기 알칼리성 축합제가 조각 형태 또는 40 내지 60%의 수용액 상태의 수산화 나트륨 또는 수산화 칼륨인 방법.
