4‐Alkenyl‐1,2,3‐thiadiazole

Abstract: Die Titelverbindungen 5 werden aus entsprechenden Alkylderivaten durch Bromierung/ Dehydrobromierung (Weg A) oder durch Wittig-Reaktion (Weg B) dargestellt. Mit 4-Phenyl-4H-1,2,4-triazol-3,5-dion entstehen unter Erhaltung des Thiadiazolrings die Monoaddukte 12. 4-Alkenyl-1,2,3-thiadiazolesThe title compounds 5 are prepared from the corresponding alkyl derivatives by bromination/dehydrobromination (route A) or by Wittig reaction (route B). 4-Phenyl-4H-1,2,4-triazole-3,5-dione yields the monoadducts 12 by mainte… Show more

“…13 The extremely high reactivity of the 1,3-diradicals 2 predestinates polymers with attached 1,2,3-thiadiazole rings for photocrosslinking reactions. Several compounds 1 with unsaturated side chains [14][15][16][17][18][19][20][21][22][23][24] and their polymers have been studied, but the non-uniform dimerization of 2, in particular the generation of 'vagabonding' sulfur atoms in primary or secondary processes has proved to be a drawback for the fabrication of negative photoresists. 20,21 Therefore, we attempted now to find systems with fairly clean photoprocesses to 9.…”
