  Abstract: M-Terphenyls are mols. with a central   Ph ring possessing at least two meta aryl substituents, most   commonly Ph or 2,4,6-trimethylphenyl. These substituents twist   out of the plane of the central Ph ring to form a bowl-shaped   environment in which a metal or functional group can be attached.   Due to the unusually effective steric protection provided by the   m-terphenyl ligands, complexes featuring these ligands often   exhibit rare or unique coordination patterns. For example, the   reaction of 2,6-bis(2,4,6-trimethylphenyl)benzoic acid with   diethylzinc gives a dimeric carboxylato complex featuring two   trigonal planar zinc centers as part of an eight-membered Zn2O4C2   heterocyclic ring. Similarly, the reaction of   2,4,6-triphenylbenzoic acid with trimethylaluminum results in the   formation of an eight-membered Al2O4C2 ring. Because of their   bulky and rigid nature, m-terphenyl ligands also have potentially   interesting uses in materials chem. The thiol-substituted   4-mercaptomethyl-2,6-diphenylbenzoic acid and   2,4,6-triphenylbenzylthiol mols. have been prepd. and their   reactions with gold surfaces and nanoparticles are being   explored.
