THIONE PHOTOCHEMISTRY. DUAL PATHWAYS IN ARALKYL THIONE CYCLIZATIONS

It is shown that aralkyl thiones, which posses an oxygen atom at the δ position in the side chain, can therefore not undergo the preferred δ insertion, and insert at the γ and ε positions.Although ε insertion occurs only from the 1(Π,Π*) state, γ abstraction ( followed by cyclization or cleavage ) occurs from both 1(Π,Π*) and 3(n,Π*) states.The quantum yields of photocyclization of 2c, 2d, and 2g change little with solvent polarity, which suggest that a thione-ether charge transfer interaction contributes little to the cyclization.Fluorescence and product quenching studies are reported which support this.
