highly reactive photoexcited triplet state of aromatic aldehyde intermediates is intercepted by the catalyst in the ground state, thus leading to the synthesis of a series of fluorenones, xanthones and thioxanthones in good to excellent yields without any external oxidants and with hydrogen as the byproduct.
