Abstract

Reactions of [Rh(CO)₂Cl]₂ with the alkynylamines Ph ≡(CH₂)₂NH₂ 1 and p-MeC₆H₄ ≡ (CH₂)₃NH₂ 2 give the corresponding alkynylamine dicarbonyl rhodium(1) chloride complexes 3 and 4 in which ligand bonding is monodentate through nitrogen. Solutions of these complexes in benzene or chloroform isomerise on standing to give complexes involving 2-substituted-pyrroline derivatives as ligands. Attempts to convert this reaction into a catalytic process were unsuccessful using rhodium catalysts at 80°C but catalysis was achieved using Ni(CO)₂(PPh₃)₂ at 125°C.
