4-Aryl-1, 2, 3-selenadiazoles when subjected to heat afforded 2, 5-diarylselenophenes and small quantities of 2,4-diarylseneophenes. Monoarylacetylenes and selenium behaved similarly. Phenylacetylene and sulfur gave 2,4-diphenylthiophene. Mechanistic aspects of these reactions are discussed.
当受热时,4-芳基-1,2,2,3-硒代二唑得到2,5-二芳基硒烯和少量的2,4-二芳基千鸟烯。单芳基乙炔和硒的行为相似。苯乙炔和硫得到2,4-二苯基噻吩。讨论了这些反应的机理。
