Each of the three independent molecules of the title compound, C~16~H~20~N~2~, has near-perpendicular benzene rings and pyramidal N atoms. Hydrogen bonding in the structure is rather inefficient.
## Abstract The synthesis of 2,2′,4,4′,6,6′‐hexanitrostilbene by oxidative coupling of 2,4,6‐trinitrotoluene in the presence of metal catalysts has been studied. The effects of reaction parameters on product yields have been evaluated and mechanisms for the reaction are proposed.
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
