The results of inelastic neutron scattering (INS), Raman and infrared (IR) studies on 1,2,4,5-tetramethylbenzene (durene), tetramethylpyrazine (TMP) and tetramethyl-1,4-benzoquinone (TMBQ) in the solid state are reported. The observed frequencies are analyzed on the basis of DFT calculations. The low frequency

A series of N-[(2,3,4,6-tetramethylbenzoyl)alkyl]imidazoles and of N-([beta-(2,3,5,6-tetramethylphenyl)-beta-hydroxy]ethyl)imidazoles has been synthesized. All compounds were tested in mice for anticonvulsant activity against electroshock and pentylenetetrazole convulsions. These durene-derivatives showed good activity, whereas the corresponding benzene-derivatives were inactive.
