Thermal Reaction of 4-(p-Aminophenyl)-1-sulfonyl-1,2,3-triazoles Furnishing Benzoyl Cyanides through N-Sulfinyl Imine Intermediates
A thermal reaction of 4-(p-aminophenyl)-1-sulfonyl-1,2,3-triazoles forming benzoyl cyanides is reported. A carbene species thermally generated from the triazole by denitrogenation undergoes intramo...
