The barrier to rotation in 2,2''-dimethyl-o-terphenyl and several 3,3''-derivatives (rational isomers of 1,2-di-o-tolylbenzene)

The synthesis and measurement of the barrier to rotation (ΔGc) in 2,2''-dimethyl-o-terphenyl (62 kJ/mol) and the following 3,3''-disubstituted derivatives is described (Cl, Cl, 74 kJ/mol), (Cl, CN, 70 kJ/mol), (CN, CN, 70 kJ/mol), (CHO, 75 kJ/mol).For 3,3''-bis-CH2Br, Δν, the separation of the -CH3 peaks in the 1Hnmr spectrum, was too small to obtain ΔGc.
