complexes with pyridine and imidazoline were synthesized by reaction of new chelating ligands (arylmethyl-imidazolidinylidene)-pyridin-2-yl-amine with boron trifluoride diethyl etherate. All the ligands and BF2 complexes were structurally characterized by IR, HRMS, 1H, 13C,11B, and 19F NMR, indicating the bidentate complexation of imidazoline nitrogen and the pyridine nitrogen to the boron center. Evaluation
通过新的螯合配体(芳甲基-咪唑啉亚基)-吡啶-2-基-胺与三氟化硼乙醚化物的反应,合成了一系列与吡啶和咪唑啉的不对称二氟-硼(BF2)配合物。所有配体和 BF2 配合物均通过 IR、HRMS、1H、13C、11B 和 19F NMR 进行结构表征,表明咪唑啉氮和吡啶氮与硼中心的双齿络合。农业生物活性评价表明,一些 BF2 复合物表现出中等的杀真菌活性,大多数 BF2 复合物表现出比非 BF2 复合底物更高的活性。© 2010 Wiley Periodicals, Inc. 杂原子化学 20:418–424, 2009; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20567
