Phenyl or m -tolyl selenoamides reacted with functionalized α-haloacetic acid in 1∶1 or 1∶2 molar ratio with no catalyst in various alcohols to undergo a selenium transfer reaction. This reaction in dif-ferent molar ratios furnished the same C—Se—Se—C coupling products with a special structure bis diselenide. A new and facile method for synthesis of such bis(alkoxycarbonyl-methyl) diselenides with the advantages of mild reaction conditions, high yields, easy availability of starting materials and good chemical selectivity was provided.
