| 3-Ethynylthiophene Usage And Synthesis |
| Uses | 3-Ethynylthiophene is used in preparation of benzothiazonines by rhodium-catalyzed denitrogenative annulation reactions of sulfonylaryltriazoles with thiochromones. | | Uses | 3-Ethynylthiophene may be used in the synthesis of the following:- 1-(2-bromobenzyl)-4-(thiophen-3-yl)-1H-1,2,3-triazole which is obtained by heating with 2-iodophenylethylazide in the presence of copper acetate monohydrate catalyst in N-methyl-2-pyrrolidone
- N-benzyl-1-phenyl-5-(thiophen-3-yl)-4-pentyn-2-amine via a multi-step reaction process
- [(C4H3S-3)C≡CAg]n, a polymeric compound obtained via reaction with silver nitrate in the presence of triethylamine in acetonitrile
- 4,5-bis(thiophen-3-ylethynyl)phthalonitrile via Sonogashira cross-coupling reaction with 4,5-dichlorophthalonitrile
