以HBF_4为BF_2源，在水相条件下，以炔烃为原料，采用氧化还原和分步经济的方法，合成了N，O-和O，O-二氟硼配合物。该方法具有产率高、底物范围广、反应条件温和、原料易得、可实现克级合成等特点。值得注意的是，这些二氟硼配合物表现出良好的荧光性能，表明它们在发光材料中的潜在应用。
A highly efficient redox- and step-economic method to synthesizeN,O- andO,O-difluoroboron complexes from alkynes under aqueous condition with HBF4as BF2source has been developed. This strategy features good yields, broad substrate scope, mild reaction conditions, readily available starting materials and gram-scale synthesis. Significantly, these difluoroboron complexes present good fluorescence properties, indicating their potential applications in luminescent materials.
