(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

A palladium complex ligated with Xantphos has been identified as an efficient catalyst for the catalytic amination of allylic alcohols, which allows the direct amination of allylic alcohols with amines to proceed at room temperature in the absence of additives. The method is compatible with a variety of functional groups and can be used to prepare a wide range of linear allylic amines in good to excellent yields with high stereoselectivities.

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.
