✦ Synopsis

Tile reactions of atylazosulfones 1 (ArN=NSO2Ar ') with tile potassium sails of (tertbutox'ycarbonyl)methyl 2 and losyllnethyl isocyanide 3 in DMSO afford 4.5-bis(tert-butoxycarbonyl)-4 and 4-tosyl-l-arylimidazoles 5, respectively. Yields of imidazoles 4 and 5 vary from moderate to excellent depending on the nature both of Ar in 1 and of the nucleophile (2 or 3) employed A comparison of the results obtained with those relevant to the reactions of the same uucleophiles with nitrosobenzene in aualogous experimental conditions provides usefid mechalustic indications on the transformation of I 1o 4 or 5.
