Quantitative oxidation of 3H-1,2-benzodithiol-3-one to 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage sulfurizing reagent) is achieved by reaction of the dithiolanone with a fourfold molar excess of dimethyldioxirane for 2-4 hours at room temperature. A one- or twofold molar excess of reagent affords the 1-oxide as the main product.
3H-1,2-苯并噻二酮的定量氧化为3H-1,2-苯并噻二酮1,1-二氧化物(Beaucage
硫化试剂)是通过该二噻烯酮与四倍摩尔过量的二甲基二氧
环己烷在室温下反应2-4小时实现的。使用一倍或两倍摩尔过量的试剂则主要生成1-氧化物作为主产物。
