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.

(CDC)-based pincer ligand scaffold is reported, along with its application to site-selective Rh(I)-catalyzed intermolecular hydroamination of 1,3-dienes with aryl and alkyl amines. To the best of our knowledge, this is the first example of the use of a well-defined CDC complex as an efficient catalyst. Transformations proceed in the presence of 1.0-5.0 mol % Rh complex at 35-120 °C; allylic amines are obtained
