The first solid-phase synthesis of benzo[1,2,3]thiadiazoles was achieved by starting from resin bound ortho bromo or iodo triazenes and using a functionalization on cleavage. Two different synergistic methods including an anionic approach and a cross-coupling approach were used for the synthesis. The resulting diazonium compounds readily underwent electrophilic cyclization yielding benzothiadiazoles, when cleaving the arenethiol resins. Cleavage from the resin with diluted trifluoroacetic acid resulted spontaneously in the desired cyclization reaction.

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 C6H4Se 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. - Keywords: PE Spectra, Short-lived Intermediates, Selenium Compounds
