| Abstract: | ![]()
A series of imidazo[2,1-b]thiazoles bearing halogens or a sulfonylurea group or an imidazolidone group, were synthesized and subjected to pre- and post-emergence herbicidal tests. 5-Bromo-6-(3-pyridyl)-2,3-dihydroimidazo[2,1-b]thiazole (4e) and 6-(2,3,4-trichlorophenyl)-2,3-dihydroimidazo[2,1-b]thiazole-5-carboxylic acid (8b) showed moderate activity in the post-emergence herbicidal tests only. |
