四种新的含氟芳酰亚胺基取代的六聚钼酸盐（n-Bu 4 N）2[Mo 6 O 18（NAr）]（Ar = 2-CH 3 -4-FC 6 H3（1）、3-CH 3 -4-FC 6 H3（2）、4-FC 6 H4（3）或2-FC 6 H4（4）），其中氟化苯基亚氨基通过Mo-N三键与六钼酸盐的Mo连接，α-八钼酸根离子与2-甲基-4-氟苯胺盐酸盐、3-甲基-4-氟苯胺盐酸盐、4-氟苯胺盐酸盐或2-氟苯胺盐酸盐在无水乙腈中反应的（N，N′-二环己基碳二亚胺）脱水方案。所有这些化合物均通过元素分析、UV-维斯、IR、1H NMR和单晶X-射线衍射分析进行了表征。初步的生物活性测试表明，这些化合物显示出有效的除草活性，特别是对一些测试植物（如芸苔（Brassica campestris L.），平卧草，稗草，和大蓟（Cirsium japonicum DC.）。
Four novel fluoro-functionalized arylimido-substituted hexamolybadates, (n-Bu4N)2[Mo6O18(NAr)] (Ar = 2-CH3-4-FC6H3 (1), 3-CH3-4-FC6H3 (2), 4-FC6H4 (3), or 2-FC6H4 (4)), in which fluorinated phenylimido group linked to an Mo of hexamolybdate by a Mo−N triple bond, have been prepared via the DCC (N,N′-dicyclohexylcarbodiimide) dehydrating protocol of the reaction of α-octamolybdate ion with 2-methyl-4-fluoroaniline hydrochloride, 3-methyl-4-fluoroaniline hydrochloride, 4-fluoroaniline hydrochloride, or 2-fluoroaniline hydrochloride in anhydrous acetonitrile. All these compounds have been characterized by elemental analysis, UV−vis, IR, 1H NMR, and single-crystal X-ray diffraction analyses. The preliminary biological activity test indicated that these compounds display potent herbicidal activity, in particular against the roots of some tested plants (such as Brassica campestris L., Eclipta prostrata L., Echinochloa crusgallis L., and Cirsium japonicum DC.).
