《Alkaline Soil Degradation and Crop Safety of 5-Substituted Chlorsulfuron Derivatives》 was published in Molecules in 2022. These research results belong to Wu, Lei; Hua, Xue-Wen; Li, Yong-Hong; Wang, Zhong-Wen; Zhou, Sha; Li, Zheng-Ming. Name: 1-Chloro-4-iodo-2-nitrobenzene The article mentions the following:

Sulfonylurea herbicides can lead to serious weed resistance due to their long degradation times and large-scale applications. This is especially true for chlorsulfuron, a widely used acetolactate synthase inhibitor used around the world. Its persistence in soil often affects the growth of crop seedlings in the following crop rotation, and leads to serious environmental pollution all over the world. Our research goal is to obtain chlorsulfuron-derived herbicides with high herbicidal activities, fast degradation times, as well as good crop safety. On account of the slow natural degradation of chlorsulfuron in alk. soil, based on the previously reported results in acidic soil, the degradation behaviors of 5-substituted chlorsulfuron analogs (L101-L107) were investigated in a soil with pH 8.39. The exptl. data indicated that 5-substituted chlorsulfuron compounds could accelerate degradation rates in alk. soil, and thus, highlighted the potential for rational controllable degradation in soil. The degradation rates of these chlorsulfuron derivatives were accelerated by 1.84-77.22-fold, compared to chlorsulfuron, and exhibited excellent crop safety in wheat and corn (through pre-emergence treatment). In combination with bioassay activities, acidic and alk. soil degradation, and crop safety, it was concluded that compounds L104 and L107, with Et or Me groups, are potential green sulfonylurea herbicides for pre-emergence treatment on wheat and corn. This paper provides a reference for the further design of new sulfonylurea herbicides with high herbicidal activity, fast, controllable degradation rates, and high crop safety.
