Nitro allylic derivatives were converted into dienes through the elimination of the nitro group under basic treatment, in the presence of a palladium catalyst. This reaction probably involves the formation of a palladium π-allyl complex followed by a base-promoted β-hydride elimination. This reaction, combined with the condensation of ketones with nitromethane and the functionalization of the resulting nitrocycloalkenes, constitutes a very powerful synthetic tool for the formation of dienes. Particular attention has been brought to the application of this methodology to the formation of 1-substituted naphthalenes from 1-tetralone.

钯引发硝基烯丙基烯丙基化合物形成二烯：萘衍生物的广泛用途†

在钯催化剂的存在下，在碱性处理下，通过消除硝基，将硝基烯丙基衍生物转化为二烯。该反应可能涉及形成钯π-烯丙基络合物，然后消除碱促进的β-氢化物。该反应与酮与硝基甲烷的缩合以及所得硝基环烯烃的官能化相结合，构成了用于形成二烯的非常强大的合成工具。特别注意了该方法在从1-四氢萘酮形成1-取代萘中的应用。
