Abstract
Irradiation of four 1-aryl-1,2-propanediones (Ia–Id) with over 300 nm light in 2-propanol gives reduction products identified to be the corresponding pinacols or hydrols formed by the reduction at the aroyl (but not acetyl) oxygen. The products from 1-(o-tolyl)-1,2-propanedione (Id) can also be accounted for by the initial hydrogen abstraction from ortho methyl by the aroyl carbonyl oxygen. Their photoreactivities are discussed as regards their electronic emission spectra and triplet configuration.
