A number of the nitro derivatives of aromatic hydrocarbons undergo reactions in trifluoromethanesulphonic acid at ca. 100 deg C in which either the nitro group undergoes a 1,3-rearrangement or cyclisation occurs to form an anthranil.The rates and product composition have been determined for reactions in which the subsituents ortho to the nitro group are methyl or ethyl.For the rearrangement reaction to occur, it appears necessary that the nitro group should be initially between two alkyl substituents.The cyclisation reaction is significant only when one of the ortho-substituents is an ethyl group.
