An organometallic complex of a tridentate bis(phosphine)-carbodicarbene ligand and a transition metal, is described. In some embodiments the ligand has the structure of Formula (I): The complexes are useful in methods of making an allylic amine carried out by reacting a 1,3-diene with a substituted amine in the presence of such an organometallic complex to produce by intermolecular hydroamination the allylic amine.

Synthesis of an azulene lactone by an intramolecular [6+4] cycloaddition
Intramolecular cycloadditions of 6-fulvenyl 2.2-dimethyl-3,5-hexadienoate produce both [6+4] and [4+2] adducts. The [6+4] adduct can be converted into an azulene lactone. Less highly substituted fulvenyl diene esters give analogous products in modest yields.
