Abstract
Amination of PtII-allene complexes of the type cis[PtCl2(Me2CCCHR)(PPh3)] gives the new four-membered C, N chelate aminoalkenyl complexes [PtC(CMe2)CHRNMe2(PPh3)Cl]. These undergo ready insertion of carbon monoxide into the CPt σ-bond; the resulting acyl complexes are oxidized by hydrogen peroxide to aminoacidato complexes, and the free unsaturated β-aminoacids can be recovered in good yield by ligand displacement. © 1980.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
