cycloaddition reaction by merging organic photoredox and Lewisacid catalysis, providing a straightforward and efficient approach for directly installing a benzofuran skeleton on the saturated aza-heterocycles. In this protocol, we also describe a novel organic photocatalyst (t-Bu-DCQ) with the advantages of a wider redox potential, easy synthesis, and a low price. Furthermore, the stepwise activation mechanism
在此,我们报告了通过合并有机光氧化还原和路易斯酸催化的光诱导脱氢/(3+2) 环加成反应,为在饱和氮杂杂环上直接安装苯并呋喃骨架提供了一种简单有效的方法。在该协议中,我们还描述了一种新型有机光催化剂 ( t -Bu-DCQ),其具有更广泛的氧化还原电位、易于合成和价格低廉的优点。此外,一系列实验和计算研究证明了双 C(sp 3 )-H 键的逐步激活机制。

The present invention relates to herbicidal compositions comprising as herbicide A at least one protoporphyrinogen-IX oxidase inhibitor (PPO inhibitor), and at least one light detoxifying compound B, compositions comprising them and their use as herbicides, i.e. for controlling harmful plants, and also a method for controlling unwanted vegetation which comprises allowing a herbicidal effective amount of said herbicidal composition to act on plants, their seed and/or their habitat.
