Abstract
Knoevenagel condensation of azulenyl ketones with malononitrile synthesized π-conjugated 1-mono- and 1,3-bis(phenyl-dicyanovinyl)azulenes, and 1-mono- and 1,3-biphenylazulenes were obtained by the Kumada cross-coupling ofbromazulenes with PhMgBr. The electronic spectra of dicyanovinylatedazulenes showed intense absorption bands of intramolecular charge transfer in the visible region, as well as significant bathochromic shifts of the absorption band maxima for phenylazulenes.
