3-取代2,4-戊二酮的配位模式考虑了取代基的化学性质和配体的构象柔韧性。给出了额外给体位点的额外和竞争性配位的例子，并讨论了这种配合物中结构重排的两种不同途径。据此推测了乙酰丙酮氰化中间产物4在其Cu和Ni配合物中的新结构
Coordination modes of 3-substituted 2,4-pentanediones are considered with respect to the chemical nature of the substituent and the conformational flexibility of the ligand. Examples of additional and competitive coordination of the extra donor site(s) are given, and two different pathways for the structural rearrangement in such complexes are discussed. Accordingly, a new constitution of the acetylacetone cyanation intermediate product 4 in its Cu and Ni complexes is speculated
