for the intermolecular coupling of 1,3-dicarbonyl compounds using ceriumammoniumnitrate in CH3CN/CH3OH/H2O has been described. The procedure provided a convenient method for the synthesis of 1,4-diketone derivatives with excellent yields (up to 96%) and powerful evidence for the oxidationmechanism mediated by ceriumammoniumnitrate.

Organometallic macrocycles based on bridge ligands with terminal imidazole groups show the formation of various patterns. The end imidazolyl finishes the conjugated system on the back bone and can freely twist or rotate just like the joints of a human body such as the knee and wrist.
