The Knoevenagel condensation reaction of benzaldehydes with nitroalkanes is a classic general method for the preparation of nitroalkenes, which are very valuable synthetic intermediates.
In the Knoevenagel condensation reaction an aldehyde or a ketone reacts with the enolate anion formed from a molecule which has an acidic hydrogen atom which is alpha to two activating groups (either a carbonyl or cyano group); the elimination of a water molecule occurs readily leading to an alpha, beta unsaturated compound.

By Knoevenagel condensation between bisformyl carbazole and bis(cyanoacetate), we can control the ring size of carbazole cyclic oligomers with a high yield.
Efficient energy transfer was observed from carbazole moieties to acceptor-substituted ones in the tetramer.
Thin films of p-sexiphenyl (6P) were doped with increasing amounts of potassium in situ, and the change in the valence electronic structure of 6P upon the alkali metal deposition was followed with ultraviolet photoelectron spectroscopy.
