SYNTHESIS OF 2-HALOGENO-2-NITROETHENYLARENES
Aleksiev, D. I.,Ivanova, S. M.
, p. 1845 - 1848 (2007/10/02)
A series of 2-halogeno-2-nitroethenylarenes were obtained as a result of the condensation of halogenonitromethanes with aromatic (heterocyclic) aldehydes in the presence of catalytic amounts of ethylenediamine and also by the addition of halogenonitromethanes to butylarylimines in acetic anhydride.
