New neutral organometallic palladium(II) complexes, [PdPhI(PNMe2)] (1), [PdPhI(PC=NMe)] (2), [PdPhI(PC=NEt)] (3), and [PdMeCl(PNMe2)] (4), [PNMe2 means N,N-dimethyl-2-(diphenylphosphanyl)aniline; PC=NMe means N-[2-(diphenylphosphanyl)benzylidene]-N-methylamine; PC=NEt means N-[2-(diphenylphosphanyl)benzylidene]-N-ethylamine} have been synthesized by oxidative addition of PhI to [Pd(dba)2] in the presence of the P∩N ligand (1-3), or by substitution reaction on [PdMeCl(COD)] with PNMe2 (4). Cationic σ-organometallic species [PdR(PPh3) (P∩N)]+ are obtained upon treating complexes of the type [PdRX(P∩N)] with PPh3 and AgCF3SO3 and consist predominantly of the trans-P,P isomer in CDCl3 solution, as shown by NMR spectroscopic studies. The cationic η3-allyl complex [Pd(η3-all)(PNMe2)]PF6 has also been prepared and characterized, both in solution and in the solid state. Compounds [PdPhI(PNMe2)] (P21/n), [PdPhI(PC=NMe)] (P1?), [PdPhI(PC= NEt)] (P1?). and [Pd(η3-all)(PNMe2)]PF6 (P1?) have been authenticated by X-ray analysis.
