摘要：Three (4)-(C=C-C=O) coordination cobalt(I) complexes 1-3 were synthesized by the reactions of cinnamaldehyde, p-fluorocinnamaldehyde, and p-chlorocinnamaldehyde with CoMe(PMe3)(4). Complex 4 as (2)-(C=C) coordination was prepared by the reaction of chalcone with Co(PMe3)(4). The structures of complexes 1-4 were confirmed by single-crystal X-ray diffraction. Although the reactions didn't undergo C-H bond activation and decarbonylation, the formation of complexes 1-4 deepens our understanding of the reactions between ,-unsaturated aldehyde or ketone with low-valent central cobalt atom.
