چکیده
The title mol-ecule, C(16)H(18)Se(2), features a diselenide bridge between two 4-methyl-benzyl units, in which the central C-Se-Se-C torsion angle is 88.1 (3)°, while the two Se-Se-C-C fragments assume gauche conformations, with torsion angles of -51.8 (5) and 59.1 (4)°. The dihedral angle between the benzene rings is 78.9 (2)°.

Synthesis and Characterization of Symmetrical and Unsymmetrical Analogues of 1,2-bis[bis(4-chlorophenyl) Methyl] Diselane
The ‘living’ species selenide anion Se2, generated in situ by the reduction of 1,2-bis(bis(4-chlorophenyl)methyl)diselane with sodium borohydride, was treated with various organic halides to afford synthetically important organoselenium compounds including α,ω-diselenoethers and selenides bearing ester functionality, under mild and neutral conditions. These compounds have been characterized ana...
متن کامل1,2-Bis(4-nitrobenzyl)diselane
The title compound, C(14)H(12)N(2)O(4)Se(2), is not chiral, but the mol-ecules assume a chiral conformation in the solid state and crystallize as an aggregate. The central C-Se-Se-C torsion angle is 90.4 (2)°, while the two Se-Se-C-C fragments assume gauche conformations with values of -59.4 (5) and 67.5 (4)°. The dihedral angle between the two benzene rings is 80.74 (14)°.

The present paper describes the synthesis of some symmetrical substituted 1-(2-chloroethyl) pyrazole-based dichalcogenides and monochalcogenides by reacting different 3,4,5-trisubstituted 1-(2-chloroethyl) pyrazole derivatives with in situ prepared Na2E2 (E = S, Se, Te) and sodium hydrogen selenide, respectively. All compounds were fully characterized by different spectroscopic techniques, name...
متن کاملAntimicrobial Activity of Quinazolin Derivatives of 1,2-Di(quinazolin-4-yl)diselane against Mycobacteria
Mycobacterium tuberculosis (M. tuberculosis) is one of the leading causes of morbidity and mortality. Currently, the emergence of drug resistance has an urgent need for new drugs. In previous study, we found that 1,2-di(quinazolin-4-yl)diselane (DQYD), a quinazoline derivative, has anticancer activities against many cancers. However, whether DQYD has the activity of antimycobacterium is still l...
