Disubstituted internal olefins are oxidized selectively to α-chloro ketones in excellent yields from the reaction with chromic anhydride-chlorotrimethylsilane in carbon tetrachloride.
Metal-Catalyzed Organic Photoreactions. One-Step Synthesis of Chlorinated Ketones from Olefins by Photooxidation in the Presence of Iron(III) Chloride

Under photooxidation in pyridine in the presence of FeCl3, mono- and disubstituted olefins gave α-chloro ketones, while tri- and tetrasubstituted olefins gave dichloro ketones with a C-C bond cleavage.The reaction was interpreted in terms of an electron-transfer mechanism occurring within the coordination sphere of the iron ion

By a combination of chromatographic methods 1 mg of pentylurofuranic acid, a dicarboxylic acid C14H20O5, was isolated from 10 l urine.According to spectroscopic measurements in combination with reactions in microscale its structure is 3-carboxy-4-methyl-5-pentyl-2-furanpropanoic acid (1a).This was confirmed by synthesis.Pentylurofuranic acid does not only occur in urine, but also in blood.Accompanying compounds differ only in the construction of the side chain in position 5.
