A convenient and expeditious strategy to synthesize difluoroboron complexes of β-keto amides has been developed from β-keto nitriles and BF3·OEt2. BF3·OEt2 serves as both a BF2 source and a Lewis acid catalyst in the synthetic strategy. The formation mechanism of the difluoroboron complexes from β-keto nitriles and BF3·OEt2 was proposed. The difluoroboron complexes can be further converted into β-keto amides by treatment with sodium acetate. The strategy features advantages such as a wide substrate scope, non-metal catalysis, and easy operation. Some of the difluoroboron complexes display good fluorescence properties in the solid state and potential application in solid-state luminescent materials.

experimental part, p. 2339 - 2343 (2009/07/18)
The catalytic hydrogenation (H2, Pd/C) of a set of BF2 complexes with a 1,3-dicarbonyl structural unit leading to monocarbonyl compounds has been studied. The transformation presented is general for the aryl-substituted derivatives and occurs under mild conditions (H2, 1 bar, 25 °C) in methanol or THF.
