Abstract:difluoro-2,4-dinitrobenzene is used as the raw material to reduce and synthesiz 7-fluoro-6-amino-1,4-benzoxyazinyl-3(4H)-ketone by etherification,the yield can reach 66.3%caculated as 1,5-difluoro-2,4-dinitrobenzene),and the structure of the final product also proved. The obtained product is the key intermediate to synthesiz the herbicide-Flumioxaxin.
Keywords:difluoro-2  4-dinitrobenzene  7-fluoro-6-amino-1  4-benzoxyazinyl-3(4H)-ketone  synthesis
