用途有機合成原料。
使用1,3-Dithiane is used in umpolung reactions such as the Corey-Seebach reaction. It acts as a reagent for the deoxygenation of sulfoxides to their corresponding sulfides. Further, it is used as a protecting group for carbonyl compounds used in organic synthesis. It serves as a useful labeled synthon. In addition to this, it is used in the preparation of 2-ethyl-[1,3]dithiane.
一般的な説明1,3-Dithiane, a protected formaldehyde anion equivalent, serves as useful labeled synthon.
純化方法Crystallise the 1,3-dithiane from 1.5 times its weight of MeOH at 0o, and sublime it at 40-50o/0.1mm. [Groel & Seebach Synthesis 357 1977, Beilstein 19/1 V 13.]
