A simple approach for preparation of dinitronaphthalene compounds from the nitration reaction of 1-nitronaphthalene with NO2 as nitration reagent

A simple method for the preparation of dinitronaphthalene from the nitration reaction of 1-nitronaphthalene with NO 2 as nitration reagent under the mild conditions has been successfully developed in this work. The results indicated that Ni(CH 3 COO) 2 ·4H 2 O catalyst shows better catalytic performances, and the conversion of 1-nitronaphthalene is 33.10 % with 34.10, 23.56, 19.30, and 3.56 % of the selectivity to 1,5-DNN, 1,3-DNN, 1,4-DNN, and 1,8-DNN, respectively, under the optimal reaction conditions. This is a mild, environmentally benign, and economical method for the preparation of dinitronaphthalene.
