Abstract
The rare earth metal (III) trifluoromethanesulfonate (rare earth metal (III) triflate, RE (OTf) 3) was found to be an efficient catalyst for aromatic nitration with carboxylic anhydride– inorganic nitrate as the nitrating agent. In the presence of a catalytic amount of RE (OTf) 3, the nitration of substituted benzenes proceeded to afford the corresponding nitrobenzenes. Especially, scandium (III) trifluoromethanesulfonate (scandium (III) triflate, Sc (OTf) 3) is ...
