‐(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).
