Diazotransferreactions are notoriously associated with the use of potentially explosive sulfonyl azides. The first ‘sulfonyl-azide-free’ (SAFE) protocol for producing diazo compounds from their active-methylene precursors via the Regitz diazotransferreaction was developed and has displayed a remarkable substrate scope. It can be applied to generating arrays of diazo compounds for further evolution
