Abstract: | The reaction of 1-substituted 2-chloroindole-3-carboxaldehydes with 1-amino-2-imidazolidinone gave a series of 1-substituted 2-chloro-3-(2-oxo-1-imidazolidinyliminomethyl)indoles which were evaluated as potential herbicides. The level of biological activity was not sufficient to warrant further investigation. |
