A direct pyridinium C-H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives with high efficiency. This transformation features the direct and efficient formation of a C═N bond with a high functional group tolerance under metal-free conditions. The spectroscopic properties potentially enable these sulfonyl iminopyridine compounds to be useful new emitting materials.
已开发出一种直接的吡啶鎓C-H磺酰亚胺化反应，用于高效合成磺酰亚胺基吡啶衍生物。这种转化的特点是在无金属条件下直接有效地形成C═N键，且具有高官能团耐受性。光谱性质可能使这些磺酰亚胺基吡啶化合物成为有用的新型发光材料。
