A series of unsymmetrical difluoro-boron(BF2) 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 of agricultural bioactivities showed that some of the BF2 complexes exhibited moderate fungicidal activities, and most of the BF2 complexes exhibited higher activities than the none-BF2 complexed substrates. © 2010 Wiley Periodicals, Inc.
