Cyanamides are an important class of molecules. This work describes a facile synthesis of disubstituted cyanamides. Here, readily accessible 1-cyano-1, 2-benziodoxol-3-(1H)-one (CBX) was applied as a stable electrophilic cyanation reagent. Diverse secondary amines were effectively cyanated. Moreover, secondary sulfonamides proved to be suitable substrates and were readily converted to N-alkyl(aryl
氰胺是一类重要的分子。这项工作描述了双取代氰胺的简便合成。在这里,容易获得的 1-cyano-1, 2-benziodoxol-3-(1H)-one (CBX) 被用作稳定的亲电氰化试剂。多种仲胺被有效地氰化。此外,仲磺酰胺被证明是合适的底物,并且很容易转化为N-烷基(芳基)-N-芳基磺酰基-氰胺,作为有机转化的重要组成部分。
