Hexamethyldisilazane was reacted with formamides to generate N,N-disubstituent formimidamide, after which a reaction with sulfonamides was induced to form sulfonylformamidines. This protocol can be applied for arylformamidine formation in which anilines are used as substrates under optimized conditions. The advantages of this method are high efficiency, structural diversity in products with good yields
六甲基二硅氮烷与甲酰胺反应生成N , N-二取代基甲酰亚胺,然后与磺酰胺反应生成磺酰甲脒。该协议可应用于芳基甲脒形成,其中苯胺在优化条件下用作底物。该方法的优点是效率高,产品结构多样,产率高,适用于大规模操作。
