Abstract

The coordination chemistry of intramolecular stannylene phosphorus Lewis pairs incorporated into four membered ring systems is presented. Previously reported coordination chemistry of stannylene and phosphorus towards palladium(0) is extended by using Pd(nbe)3 as a precursor, yielding co-ligand free complexes. An equilibrium of one or two stannylene phosphorus ligands coordinated to Pd(0) was observed with tin acting either as a donor or an acceptor towards palladium. Furthermore, the reactions with transition metal(I) chlorides, [(cod)IrCl]2, [(cod)RhCl]2 and Me2SAuCl are reported. They proceed via insertion of stannylene into the M–Cl bonds, yielding metal complexes with chelating stannide phosphorus ligands. For gold, a dinuclear complex with bridging P–Sn ligands was formed. Furthermore, the reaction of a P → Sn Lewis pair in a three membered ring system with (cod)PtMe2 is reported.
