Experimental study demonstrates copper-catalyzed aerobic synthesis of sulfinic esters from sulfonyl hydrazides and alcohols, highlighting a versatile pathway for chemical transformations.
A Cu-catalyzed aerobic oxidative reaction between sulfonyl hydrazides and alcohols has been developed. In this reaction, sulfonyl hydrazides act as the sulfinic acid precursors to react with alcohols, resulting in sulfinic esters with up to 72 % yield. This catalytic system tolerates a wide range of sulfonyl hydrazide substrates, and represents a new strategy for the transformation of readily available sulfonyl hydrazides.
