ABSTRACT
A visible-light induced dearomative cascade cyclization of biaryl ynones with diselenides under photocatalyst and external additive-free conditions has been explored, giving a series of selenated spiro[5.5]trienones in moderate to good yields. The Se-Se bond in diselenides could be cleaved to generate arylselenyl radicals under visible light irradiation in the absence of a photocatalyst. This protocol provides a facile and green method for the synthesis of spiro[5.5]trienones.
