| Abstract: | New bisconjugated compounds, 1, 3-bis (aryl butadienyl ketone) propane derivatives with F, Cl, Br, and 2-naphthyl substituents, were synthesized via double Wittig reactions. Their visible light irradiated photocatalytic intramolecular4+4]and2+2]cycloadditions were realized in the presence of Ru(bipy)3Cl2 as catalyst. |
