M-terphenyl

This metathetical route was recently extended to the synthesis of amidinato complexes of Al, Ga, and In containing very bulky amidinate ligands with 2,6-Pr CgHs, adamantyl, m-terphenyl or 9-tiiptycenyl substituents at the central carbon atom. ... 

Prior to 1995 no such inorganic compound, save perhaps for borazine, could boast of aromaticity. The utilization of m-terphenyl sterically demanding ligands in organogallium chemistry would change this forever.

Data for a series of [Ru(ri6-arene)Cl(en)](PF6) complexes with the isomeric p-, o-, and m-terphenyls mirrored these observations (74). The complex with the most extended arene (p-terphenyl, 14) was the most potent, with potency similar to cisplatin, but is not cross-resistant, and has a much higher activity than its isomeric complexes. Again, no cross-resistance with cisplatin was observed for these complexes (74). 

Fujimoto et al. [77] synthesized a novel phase by coupling a dodecylamino-substituted P-cyclodextrin (P-CD) to 3-glycidoxypropyl-derivatized silica gel. The surface coverage of this phase was reported as 0.37 xmol/m, which amounts to a surface coverage of 2.6 xmol/m for C12 chains (seven chains per fi-CD). An increase in shape selectivity was observed when compared with a conventional Cis monomeric phase as determined by selectivity differences between j9/m-terphenyl, j9/o-terphenyl, and coronene/phenanthro[3,4-c]phenanthrene solute pairs and was attributed to the localized high ligand density as constrained by the fi-CD platform structure. 

High molecular weight often results in an increase in thermal stability, probably from the increase in melting point - decomposition is much more rapid in a melt than in the solid phase. 2,2, 2",4,4, 4",6,6, 6"-Nonanitro-m-terphenyl (NONA) (158) is synthesized from the Ullman... 

Similar routes have been used for the synthesis of other polynitrophenylenes. 1,3,5-Tris(2,4,6-trinitrophenyl)-2,4,6-trinitrobenzene (160) is synthesized from the reaction of 1,3,5-trichloro-2,4,6-trinitrobenzene with three equivalents of picryl chloride in the presence of activated copper powder in refluxing mesitylene. " 2,2",4,4, 4",6,6, 6"-Octanitro-m-terphenyl (161) has been synthesized from picryl chloride and l,3-dichloro-4,6-dinitrobenzene. ...
