Irradiations of alkyl phenylglyoxylates with sulfur-containing carboxylates yielded the corresponding photodecarboxylative addition products in moderate to good yields of 26-58%. Reductive photodimerization competed with decarboxylative addition in all ca

Three new photoproducts, ethyl O-benzoyl mandelate (5a), ethyl O-acetylmandelate (6a), and biphenyl triketone (7a) are isolated and identified in the reactions of ethyl phenylglyoxylate (1a) in benzene. Quantum yields and initial rate constants of product formation are shown to be concentration dependent. For the formation of carbonyl product 3 at lower starting material concentrations (N) and intermolecular H abstraction (k1) of methyl phenylglyoxylate (1d) are measured.

The hydrogenation of ethyl phenylglyoxylate catalyzed by bis(dimethylglyoximato)cobalt(II)-quinine gave a novel reductive dimerization product, diethyl diphenyltartrate, with a slight optical activity.The crystals obtained from its benzene-hexane solution were investigated by X-ray diffraction method.The crystal is triclinic, space group p1, a = 10.078(3), b = 10.283(2), c = 9.781(3) Angstroem, α = 109.80(2), β = 102.35(3), γ = 78.50(2), Z = 2, V = 922.7 Angstroem3, Dc = 1.29 g cm-3, μ = 7.46 cm-1 for Cu Kα.The structure was solved by the direct method, and refined by a block-diagonal least-squares procedure: R = 0.059 for 2568 reflections with /Fo/ >3?(/Fo/).The relative configuration around the two chiral carbons indicated that the molecule is in the threo-form, and the Newman projection showed that the molecule has the staggered conformation.There were two relatively strong intermolecular hydrogen bonds between the two hydroxyl groups and the two carbonyl oxygen atoms of ethoxycarbonyl groups.
