A convenient, highly efficient and green approach for synthesis of tetraketones from aromatic aldehydes with dimedone and 1,3-indanedione at room temperature in PEG-400 is described. The use of PEG-400 as the reaction medium and avoiding the use of any ca

New Aspects in the Reaction of Azomethines with Cyclic CH-Acidic Compounds

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.
