摘　　要：2,4,6-Triarylpyrylium salts are stable,readily available and cheap.However,only their electron transfer oxi-dation ability has been explored.We herein report that they could perform both energy transfer and elec-tron transfer activation modes for the photocascade E→Z isomerization/cyclizations,E→Z isomerization of activated alkenes and oxidative cyclizations.
