difluorinated tetra- and pentabromo BDE internal standards for GC–MS/GC–ECD analysis, 2F-BDE47, 2F-BDE85, 2F-BDE99 and 2F-BDE119, have been prepared in 98–99.0% purity, mainly by coupling of the new tribromodifluorophenols (19–21) and symmetrical bromodiphenyliodonium salts (8, 22). The four difluorinated BDEs showed promising properties as internal standards for quantitative BDE analysis. Tetra-, penta-, hexa-
