Synthesis, Characterization, and Agricultural Biological Activities of 5‐Fluoro‐2‐hydroxy Butyrophenone

Journal of Chemistry, Volume 2013, Issue 1, 2013., 2013
A novel synthetic approach towards 5‐fluoro‐2‐hydroxy butyrophenone is reported. Using 4‐fluorophenol as a raw material, the processes of etherification protection, Friedel‐Crafts acylation and demethylation provide the target compound under mild conditions.

Effects of Photosystem‐II‐Interfering Herbicides Atrazine and Bentazon on the Soybean Transcriptome

The Plant Genome, Volume 2, Issue 2, July 2009., 2009
Atrazine and bentazon are both photosystem‐II (PSII)–inhibiting herbicides that interfere with photosynthetic electron transport, provoking oxidative stress. While atrazine is lethal to soybean [Glycine max (L.) Merr.], bentazon does not kill soybean because of the capability of soybeans to metabolize the herbicide.
