Abstract
N2 the mild: Diazo compounds are extremely versatile intermediates for synthetic organic chemistry, but their synthesis can be challenging in the presence of delicate functional groups. The Staudinger ligation has inspired a mild method for the conversion of a broad range of azides into their diazo compound derivatives through an acyl triazene intermediate.
