Description/Abstract

An isomeric series of seven, square-planar, neutral dichloropalladium(II) complexes cis-PdCl2{P,P-C6H3N(CH2PPh2)2(CO2H)(OH)} 2a–2g have been synthesised in high yields (70–99%) from PdCl2(cod) (cod = cycloocta-1,5-diene) and the appropriate ligands C6H3N(CH2PPh2)2(CO2H)–(OH) 1a–1g in CH2Cl2. The new ditertiary phosphine C6H3N(CH2PPh2)2(3-CO2H)(4-CO2H) 3, bearing two remote carboxylic acid groups on the N-arene backbone, was prepared by condensation of H2NC6H3(3-CO2H)(4-CO2H) with 2 equiv. of Ph2PCH2OH in MeOH. The palladium(II) complex cis-{P,P-PdCl2C6H3N(CH2PPh2)2(3-CO2H)(4-CO2H)} 4 was synthesised in an analogous fashion to 2a–2g. Solution NMR (31P{1H}, 1H), FT-IR, ms and microanalytical data are in full agreement with the proposed structures.
