Disclosed is a novel method for the preparation of aromatic organic diselenide compounds. The method involves reacting an alkali metal diselenide with certain halogenated aromatic compounds in dimethylformamide to form the corresponding aromatic diselenide. The use of dimethylformamide enables one to prepare certain aromatic diselenide compounds containing two replaceable halogen atoms in a one-step process.

groups on the alkyl group were transformed efficiently into the corresponding carbonylcompounds, particularly primary alkyl aryl selenides in good yields, by a simple photolysis in the presence of air or oxygen. This transformation can be conducted without protection of functional groups. The yield of carbonylcompounds was much affected by the solvent viscosity, reaction temperature, concentration
