of a controllable, base-free, one-pot Curtius rearrangement using 1,1-dimethyl-2,2,2-trichloroethoxycarbonyl azide (DMTN3) with 4-(dimethylamino)pyridine (DMAP) as a catalyst. The scope of this catalytic process covers a range of primary, secondary, and tertiary alkyl and aryl carboxylic acids that allow the efficient stereospecific construction of alkyl or aryl isocyanates. Examples are reported of
