Abstract:A series of unsymmetrical difluoroboron(BF(2)) 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 BF(2) complexes were structurally characterized by IR, HRMS,(1)H, (13)C, (11)B, and (19)F NMR, indicating the bidentate complexation of imidazoline nitrogen and the pyridine nitrogen to the boron center. Evaluation of agricultural bioactivities showed that some of the BF(2) complexes exhibited moderate fungicidal activities, and most of the BF(2) complexes exhibited higher activities than the none-BF(2) complexed substrates.
