Reactions of 2-Nitro- and 2-Bromo-2-nitroethenylphosphonates with Anthracene

Bis(2-chloroethyl) 2-nitro- and 2-bromo-2-nitroethenylphosphonates react with anthracene along two competing pathways: 4+2] cycloaddition and electrophilic substitution; in the case of the bromo derivative, the resulting products undergo dehydrobromination under the reaction conditions to form anthracene- and dihydroanthracene-containing nitroethenylphosphonates.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 5, 2005, pp. 729–733.Original Russian Text Copyright © 2005 by Anisimova, Kuzhaeva, Berkova, Deiko, Berestovitskaya.
