Abstract
A series of 4-(alkylamino)-1, 2, 4-triazoles transfer the alkylamino group to the 4-position of nitrobenzene and various 3-substituted nitrobenzenes, with no detectable ortho substitution. By contrast 2-nitrothiophene reacts in the 3-position and 2-nitronaphthalene in the 1- position; 1-nitronaphthalene gives a mixture of products derived from dominant 2-with some 4-substitution. The orientations are discussed and rationalized.
