Diarylamines are obtained directly from sulfinamides through a novel rearrangement sequence. The transformation is transition metal-free and proceeds under mild conditions, providing facile access to highly sterically hindered diarylamines that are otherwise inaccessible by traditional SNAr chemistry. The reaction highlights the distinct reactivity of the sulfinamide group in Smilesrearrangements
二芳基胺是通过一种新的重排序列直接从亚磺酰胺中获得的。该转化不含过渡金属,在温和条件下进行,可轻松获得传统 S N Ar 化学无法获得的高度空间位阻二芳基胺。该反应突出了 Smiles 重排中的亚磺酰胺基团与更常见的磺酰胺的不同反应性。

Abstract A procedure for the synthesis of N-alkyl-, N-cycloalkyl-, N,N-dialkyl-, and N-arylarenesulfinamides from the corresponding sulfenamides using KF/m–chloroperoxybenzoic acid (CPBA) in CH3CN-H2O is described. High efficiency (fast reactions, ease of manipulation, and good yields) and absence of overoxidation are the major advantageous features of this protocol. GRAPHICAL ABSTRACT
