摘要：

The Ni acetylacetonate-catalyzed addition of acetylacetone to malononitrile was shown to afford 3-acetyl-2-amino-4-hydroxy-1,3-pentadienecarbonitrile. The diphenyl boron chelate of the latter with a beta-diketone-type structure was obtained. E,Z-isomerism of the chelate and the free ligand were investigated. The Z-isomers were found to dominate in low polarity solvents.
