Hydrogenation of BF2 complexes with 1,3-dicarbonyl ligands
摘要:
The catalytic hydrogenation (H-2, 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 (H-2, 1 bar, 25 degrees C) in methanol or THF. (C) 2009 Elsevier Ltd.

synthesize difluoroboron complexes of β-keto amides has been developed fromβ-ketonitriles 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 fromβ-ketonitriles and BF3·OEt2 was proposed. The difluoroboron complexes can be further converted into β-keto amides by treatment with sodium acetate
