An efficient Fe(III), l -valine, and 4-OH-TEMPO catalytic system was found for the oxidation of alcohols followed by condensation with sulfinamide or sulfonamide in one pot for the synthesis of N-sulfinyl- and N-sulfonylimines compounds under mild conditions. This transformation accommodates a variety of substrates, shows high functional-group tolerance, and affords the corresponding products in good to excellent yields.

通过醇与亚磺酰胺或磺酰胺的氧化级联反应，Fe(III)/l-缬氨酸催化一锅法合成 N-亚磺酰基-和 N-磺酰亚胺

发现了一种有效的 Fe(III)、l-缬氨酸和 4-OH-TEMPO 催化体系，用于醇的氧化，然后在一个锅中与亚磺酰胺或磺酰胺缩合，合成 N-亚磺酰基-和 N-磺酰亚胺化合物。条件温和。这种转变适用于各种底物，显示出高官能团耐受性，并以良好到优异的产率提供相应的产品。
