Özet

New allyl-palladium tetraalkyl(phenyl)diphosphine disulfide complexes, [(eta(3)-CH2CMeCH2)Pd(tmps)]Cl, [(eta(3)-CH2CMeCH2) Pd(teps)]Cl, [(eta(3)-CH2CMeCH2)Pd(tpps)]Cl, [(eta(3)-CH2CMeCH2) Pd(tbps)]Cl, [(eta(3)-CH2CMeCH2)Pd(tPhps)]Cl, and [(R2P(S)P(S) R-2) R=Me, (tmps); Et, (teps); Pr-n, (tpps); Bu-n, (tbps); Ph, (tPhps)] have been prepared from the addition of tetraalkyl (phenyl) diphosphine disulfide to [(eta(3)-CH2CMeCH2)Pd(mu-Cl)](2). All the complexes have been characterized by elemental analysis, Fourier-transform infrared (FT-IR), nuclear magnetic resonance (H-1-NMR and P-31-{H-1}-NMR) spectroscopy, and fast atom bombardment (FAB) mass spectrometry. The spectroscopic studies suggest that ligands are cis-chelate bidentate coordination, forming five-membered Pd-S=P-P=S palladacycles, with the eta(3)-allyl group completing the coordination sphere.
