A synthetic method to prepare azulen-1-yl ketones was developed via oxidativecleavage of the C–Cdouble bond in the reaction of easily obtainable N-sulfonylenamides with Cs2CO3 under air and natural sunlight and in the absence of a photosensitizer. Oxidativecleavage of C–C triple bonds was also demonstrated for the synthesis of azulen-1-yl ketones via a tandem Cu-catalyzed [3 + 2] cycloaddition

The Knoevenagel condensation of azulenyl ketones with malononitrile resulted in the synthesis of π-conjugated 1-mono- and 1,3-bis(phenyldicyanovinyl)azulenes, and the Kumada cross-coupling reaction of bromazulenes with PhMgBr gave 1-mono- and 1,3-biphenylazulene. The electronic spectra of dicyanovinylated azulenes showed strong absorption bands of intramolecular charge transfer in the visible region
