Synthesis of Sulfonyldiazomethanes and Acetyldiazomethanes via an Alumina-Mediated Decarboxylation Strategy

Abstract

Diazo compounds are widely adopted in organic synthesis due to their carbine characteristics. One of the most interesting diazo compounds is diazolsulfonyl. Here, in the current study, we found that diazolsufonyl compounds could be prepared with moderate to excellent yield through decarboxylation of diazosulfonyl acetates by neutral alumina. We hope that this mild and simple method might inspire wider application of these useful compounds.
