‐(Diadamantylphosphanyl)diaminocarbene and Related Ligands: Synthesis and Catalytic Applications in Intermolecular Alkyne Hydroaminations
iminophosphane 9, which is also accessible from carbene 5 upon rearrangement under heating. Stable chelate PdII complexes are synthesized using both carbene 5 and iminophosphane 9 as ligands. The complex with ligand 9 displays very promising catalytic performance in the intermolecular hydroamination of alkynes with primary arylamines.

Two very distinct chemical reactions, yet a single catalyst: A goldcomplex promotes the formation of tertiary enamines from a variety of terminal and internal alkynes. Subsequent addition of a terminal alkyne to the reaction mixture affords allenes (see scheme).

nonenolizable Pd(II) and Ni(II) imine−phosphine complexes have been synthesized and tested in the ethylene polymerization. These catalysts show improved temperature stability with respect to the corresponding diimine complexes. Nickel imine−phosphine precatalysts containing gem-dimethyl substituent α to phosphorus display moderate activity and produce substantially higher molecular weight polyethylene compared
Late transition metal complexes of certain ligands which contain phosphinidine and/or imine groups are useful as components of polymerization catalysts for olefins. Useful metals in the complexes include Ni, Pd, Fe and Co. Oligomers and/or polymers of olefins such as ethylene can be made.
