Chalcones can serve as C2 or C3 components for the formation of 1H-pyrroles. In particular the reaction with tosylisocyanid could be applied to the oligochalcones 2d-g with up to 6 enone units. A series of cross-conjugated oligomers 8d-g was obtained; these compounds consist of a chain of 1,4-phenylene, carbonyl and 1H-pyrrole-3,4-diyl building blocks. The benzene rings bear two propoxy sidechains in order to enhance the solubility.

Transition-metal-catalyzed cross-coupling reactions are a powerful tool to construct carbon-carbon bonds in modern synthetic chemistry. Chromium catalysis is much less developed compared with the widely used palladium and nickel catalysis. Herein, we repo
