trans,trans-Dibenzylideneacetone was used as an additive in the copper-catalyzed-arylation of imidazoles. It is a reactant involved in Nazarov-like cyclization, Transfer hydrogenation, Lewis acid mediated condensation, Hetero-Diels-Alder reactions, Asymmetric 1,4-addition reactions and Michael addition reactions.
