Naphthalene was nitrated with a variety of nitrating agents comparison of data with perrin's electrochemical nitration [perrin, c l (1977) j am chem soc 99, 5516-5518] shows that nitration of naphthalene gives an α-nitronaphthalene to β-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. 3) 4) the nitration of naphthalene yields 1-nitro (and rarely 2 nitro) naphthalene because the alpha site is preferred references: pavia, donald, gary lampman, george kriz, and randall engel introduction to organic laboratory techniques: a microscale approach. The nitration of 1,3,5-trimethoxybenzene produced the nitrated dimer, 2,4,6,2’, 4’,6’-hexamethoxy-3-nitrobiphenyl, which was not isolated in other solid-phase nitration in the cases of naphthalene derivatives, the α-nitrated compounds were obtained.
