A synthesis of meta-terphenyl-2,4,6,2',5',2",4",6''-0, has been carried out. From iodobenzene-2,4,6-D, and 2,6-dibrorno-l,4-dinitrobenzene, the compound 2',5'-dinitro-meta-terphenyl-2,4,6,2'',4'',6''-D, is formed (Ullmann reaction). By reduction of the nitrogroups and subsequent reductive diazotizat
