Solid state nuclear magnetic resonance, 13(3), 137-148 (1999-02-19)
One- (1-D) and two-dimensional (2-D) carbon-13 NMR exchange measurements in powder samples of isotopically normal durene under magic angle spinning (MAS) are reported. The experiments include rotor synchronized 2-D exchange (RS2DE), 1-D magnetization transfer (MT) and time reverse ODESSA (tr-ODESSA).

Journal of inorganic biochemistry, 28(2-3), 125-135 (1986-10-01)
Solution equilibria are presented for in situ reactions of the type FeII(porp) + B----FeII(porp)B, where porp represents the dianion of some durene-capped porphyrins with variable length linking methylene straps, and B is 1-methyl, 1,2-dimethyl, or 1,5-dicyclohexylimidazole.

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.

Il Farmaco; edizione scientifica, 34(9), 789-801 (1979-09-01)
A series of substituted 2-(2,3,5,6-tetramethylbenzyl)imidazolines and related compounds have been synthesized to study the steric and hydrophobic effects on the vasoactivity of the introduction of four methyl groups on the phenyl moiety. The 2-(2,3,5,6-tetramethylbenzyl)imidazoline (I) showed a high hypertensive activity
