Abstract
6,7‐Disubstituted indolizine‐5,8‐diones showed activity as herbicides, giving rapid desiccation symptomology in whole‐plant tests and bleaching in leaf‐disc assays. In isolated chloroplasts, such compounds initiated rapid uptake of oxygen in Photosystem I. A redox mediator mode of action was further supported by electrochemical studies. Several compounds described had low photostability, high volatility, hydrolytic instability or reactivity with glutathione. The detrimental effects that these factors may have had on expression of herbicidal activity are discussed. Copyright © 2004 Society of Chemical Industry
