Claims (10)

  1. 구조식(Ⅱ)의 1,2-디티올을 구조식(Ⅲ)의 α-하이드록시 케톤과 반응시키고 물을 방출하여서 구조식(I)의 2,3-디하이드로-1,4-디티인을 제조하는 방법.
    상기 식에서,
    R1및 R2는 수소이거나 혹은 C1-C6의 알킬기로서 서로 같거나 다를 수 있으며, 또는 이들이 서로 결합하여 3개 또는 4개의 메틸렌기를 갖는 고리를 형성할 수도 있고,
    R3및 R4는 수소이거나 혹은 C1-C10의 알킬기로서 서로 같거나 다를 수 있으며, 이때의 알킬기는 저급 알콕시기로 치환될 수도 있다.
  2. 제1항에 있어서 상기 반응이 산 촉매의 존재하에 수행되는 방법.
  3. 제2항에 있어서 상기 촉매가 p-톨루엔설폰산인 방법.
  4. 제2항에 있어서 상기 촉매가 메탄설폰산인 방법.
  5. 제1항에 있어서 반응시 생성된 물이 공비(共沸)에 의하여 제거되는 방법.
  6. 제5항에 있어서 벤젠, 톨루엔 또는 크실렌으로 부터 선택된 용매가 반응 혼합물내에 존재하는 방법.
  7. 제1항에 있어서 R1및 R2는 메틸기이며 R3및 R4는 수소원자인 방법.
  8. 제1항에 있어서 R1,R2,R3는 메틸기이며 R4는 수소원자인 방법.
  9. 제1항에 있어서 R1및 R2는 메틸기이고 R3는 에틸기이며 R4는 수소원자인 방법.
  10. 제1항에 있어서 생성된 디하이드로 디티인이 적당한 산화제 처리에 의하여 대응하는 산화된 디티인으로 전환되는 방법.
    ※참고사항:최초출원 내용에 의하여 공개하는 것임.
