Diselenium dibromide

Finally, selenophenes have been prepared by treatment of zirconium metallocenes (e.g., 134) with diselenium dibromide (Se2Br2> <1994JA1880> or Se(SeCN>2 <1999AGE1604, 2000JA5052>. [Pg.996]

Diselenium dichloride and seleninyl chloride both explode on addition of potassium [1,3], while the metal ignites in contact with phosphorus trichloride vapour or liquid [2], Mixtures of potassium with sulfur dichloride or sulfur dibromide, phosphorus tribromide or phosphorus trichloride, and with phosgene are shock-sensitive, usually exploding violently on impact. Potassium also explodes violently on heating with disulfur dichloride, and with sulfur dichloride or seleninyl bromide without heating [3]. [Pg.1727]

In the case of hydrogen disulfide, the S—S bond length as determined by Stevenson and Beach (211) from electron diffraction indicates that branching does not occur. Electron diffraction studies by Palmer (184) and Guthrie (188) on disulfur dichloride show an unbranched, nonplanar structure. Smyth (206) has discussed the dipole moments of hydrogen disulfide, disulfur dichloride, and diselenium dichloride on the same basis and Hooge and Ketelaar (145), the vibrational spectra of hydrogen disulfide and disulfur difluoride, dichloride, and dibromide.
