N2 - Direct sulphonation of 2-(diphenylphosphino)benzenesulphonic acid was extensively studied. The non-symmetrically functionalised reaction products obtained, related to the widely applied water soluble phosphine ligands m,m,m-TPPTS and m,m-TPPDS, display chelating κ2-(P,O)- coordination to Pd(ii) metal centres. Phase transfer reaction of rac-o,m-TPPDS as the potassium salt with 18-crown-6 and complexation to Pd(ii) gives the novel anionic catalyst precursor [K(18-crown-6)]2[κ2(P,O) {rac-o,m-TPPDS}PdMeCl] suitable for olefin polymerisation reactions. Ethene homo- and co-polymerisation reactions with polar functionalised olefins were investigated with this anionic phosphine sulphonate Pd(ii)-based pre-catalyst salt.
