A 4 - chloro - 2 - fluoro phenyl synthesis method (by machine translation)

The present invention provides a 4 - chloro - 2 - fluoro phenyl synthesis method, the method is to 4 - chloro - 2 - fluoro aniline, acetone is nitrogen and water as raw materials, reaction at certain temperature synthesis of 4 - chloro - 2 - bromobenzene

Design, Synthesis, and 3D-QSAR Analysis of Novel 1,3,4-Oxadlazol-2(3H)-ones as Protoporphyrlnogen Oxidase Inhibitors

Protoporphyrlnogen oxidase (PPO, EC 1.3.3.4) has been Identified as one of the most significant action targets for a large chemically diverse family of herbicides that exhibit some Interesting characteristics, such as low use rate, low toxicity to mammals, and low environmental Impact. As a continuation of research work on the development of new PPO Inhibitors, some benzothlazole analogues of oxadlargyl, an Important PPO-lnhlbltlng commercial herbicide, were designed and synthesized by ring-closing of the substltuents at the C-4 and C-5 positions. The bloassay results Indicated that the series 8, 9, and 10 have good PPO Inhibition activity with kl values ranging from 0.25 to 18.63 μM. Most Interestingly, 9I, ethyl 2-((5-(5-fert-butyl-2-oxo-1,3,4-oxadlazol- 2(3H)-yl)-6fluorobenzothlazol-2-yl)sulfanyl) propanoate, was Identified as the most promising candidate due to Its high PPO Inhibition effect (kl 1.42 ,μM) and broad spectrum postemergence herbicidal activity at the concentration of 37.5 g of al/ha.
