Popis:	It was established that the reaction of hexabromo-2,2′-dithienyl with magnesium in the presence of ethyl bromide gives an organodimagnesium derivative, which reacts with oxalic acid esters to give 3,3′,4,4′-tetrabromo-5,5′-dithienyl-diglyoxalic acid esters. Reduction of the latter with ethylmagnesium bromide leads to 3,3′,4,4′-tetrabromo-5,5′-dithienyl-2,2′-diglycolic acid esters.
