| Gasphasen-Reaktionen, 35 [1] Benzseleniren als kurzlebiges Zwischenprodukt in der Pyrolyse von 1.2.3-Benzoselenodiazol zu 6-Fulvenselon Benzselenirene as Short-lived Intermediate in the Pyrolysis of 1,2,3-Benzoselenodiazole to 6-Fulvenselone  | | | | Abstract
| In the pyrolysis of 1,2,3-benzoselenodiazole using a short-distance furnace, a short-lived intermediate is detected photoelectron spectroscopically. Mass spectra recorded under similar conditions suggest an isomer CöHiSe rearranging to the more stable final product 6-fulveneselone. The ionization pattern obtained by computerized spectra stripping is assigned to benzselenirene by molecular radical cation state comparison based on MNDO calculations. | | | |

| Bromierung von "Poly(l,4-diselenobenzol)" | | | | Abstract
| Poly(l,4-diselenobenzene)", obtained by reaction of 1,4-dibromobenzene with disodiumdi-selenide is shown to contain many different polymer sequences. Bromination of the polymer yields a variety of low molecular weight species thus confirming the non-uniformity of the polymer and giving some hints about its composition. The aryl-selenium-bromine compounds 1,4-benzene-diselenenyldibromide, 4,4'-di(bromoselenenyl)-diphenylseleniumdibromide, and bromo-bis(4-bromophenyl)selenonium hexachloroantimonate were fully characterised inclu ding X-ray structure determinations. | | | |
