Article abstract of DOI:10.1007/BF00816851

Treatment of substituted benzylidene anilines 1a - f with cyclic CH-acidic compounds 2a - m in ethanol at room temperature yields in addition/elimination reactions the corresponding arylidene derivatives 4 and the 2:1 adducts 5.The addition products 3, which are formed as intermediates, could not be isolated in any case.The donor/acceptor effect of the substituents on the benzylidene moiety influences to a significant extent the reactivity towards the azomethine carbon. Keywords.Azomethine; CH-Acidic compound; Addition/elimination reaction.
