Résumé

The syntheses of complexes containing the HL ligands N,N′-di-p-tolylformamidine (TolNCHNHTol) (Tol = p-MeC6H4) and N,N⇔-di-p-tolyltriazene (TolNN- NHTol) are described. The complexes are of the types cis-[Pd(C6F5)2(HL)2], trans-[Pd(C6F5)Cl(HL)2] and cis-[Pd(C6F5)2(PPh3)(HL)], with the HL ligands acting as monodentate ligands via the imino N atom. A N,N′-di-p-tolylformamidinato complex, cis-(NBun 4) | Pd(C6F5)2{N(tol)CHN(Tol)} | is also described. It undergoes irreversible insertion of CNTol of CS2, or reversible insertion of CO2, into one NPd bond. While the CS2 insertion product is an S,S-bonded dithiocarbamate-type complex, the product arising from the CO2 insertion contains a six-membered palladiacycle with the ligand O,N-bonded to the Pd atom. © 1987.
