In the title compound, C17H15BrO2S, both the benzo-furan and 2-bromo-phenyl rings are virtually planar, with r.m.s. deviations of 0.009 (2) and 0.006 (2) Å, respectively. The dihedral angle between these mean planes is 89.31 (7)°. In the crystal, mol-ecules are linked via pairs of C-H⋯π inter-actions into inversion dimers. These dimers are further linked by C-H⋯π inter-actions into supra-molecu...

significance as calcium-channel modulators in the treatment of cardiovascular diseases, such as hypertension, cardiac arrythmias or angina.1 In recent years, interest has also been focused on aza-analogs of dihydropyridines, such as dihydropyrimidines, which show a very similar pharmacological profile to that of dihydropyridine calcium channel modulators.2 In a continuation of these studies, ri...

The binuclear title complex, [Zn(2)(C(22)H(28)N(3)O)(2)(C(3)H(9)OSi)(2)], has a crystallographic imposed centre of symmetry. The Zn(II) atom is coordinated by three O and one N atom from one 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentyl-phenolate ligand and two bridging trimethyl-silanolate anions in a distorted tetra-hedral geometry. The dihedral angle between the benzotriazole ring system and t...

reactions of peroxidized chemiluminescent compounds, 5arylamino-1,2,4-trioxanes 4 (Fig. 1).1 The 1,2,4-trioxanes were synthesized by autoxidation of the imines, 3, in the presence of isobutylaldehyde. The crystal structure of this curious compound had already been determined by X-ray diffraction. We continued to investigate the reaction and found that the reaction patterns in the absence of oxy...
