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.

A short, mild, and highly chemoselective addition of organolithiumreagents to a BF2 complex of 3-oxopropanoates has been developed. The methodology allows straightforward preparation of various 1,3-dioxa-BF2 complexes and subsequently leads to the formation of 1,3-diketones starting from the corresponding 3-oxopropanoates.
