Under nitrogen atmosphere, a simple and efficient procedure for the synthesis of symmetrical selenides has been developed by the reaction of aryl or alkyl halides with magnesium (1.5 equiv) and elemental selenium (1.0 equiv) in the absence of catalyst and ligand in THF and toluene under reflux at 86°C. This protocol has been utilized for the synthesis of a variety of symmetrical selenides in good to excellent yields. ARKAT-USA, Inc.

A selenium transfer reaction from selenous acid to benzyl and alkyl halides is initiated in the presence of stannous chloride and a catalytic amount of cupric chloride resulting in the formation of the corresponding diorganoselenides and/or diorganodiselenides as the major products as indicated by 1H, 13C, 77Se NMR, and MS. The reaction is characterized by a dual-metal effect at the selenium activation and transfer step. Thus, initial reaction of stannous chloride, cupric chloride, and selenous acid gives rise to α-Cu2Se. Selenium transfer from the latter to the organic halide takes place with additional assistance of stannous chloride. Copyright Taylor & Francis Group, LLC.
