O-Sulfonylation of the o- or p-quinoid diazoketones 1a-c or 3a-c, respectively, with trifluoromethanesulfonic anhydride yields o- or p-(trifluoromethylsulfonyloxy)arenediazonium salts, respectively.The heterocyclic α-diazocarbonyl compounds 5a,b react analogously.As all (trifluoromethylsulfonyloxy)arenediazonium salts are hydrolyzed easily, azo coupling reactions have to be performed in a nonaqueous solvent.
