Abstract

The syntheses of potassium 2-(2′-methoxynaphth-1′-yl)-3,4- dimethyl-5-phenylphospholide 4 and η⁵-pentamethyl- cyclopentadienyl{η⁵-2-(2′-methoxynaphth-1′-yl)-3, 4-dimethyl-5-phenylphospholyl}-ruthenium(II) 5 and -iron(II) 6 are described. The barrier to rotation of the naphthyl group (79 kJ mol^-1 and 72 kJ mol^-1 in CD₂Cl₂ respectively) characterises 5 and 6 as potential 'tropos' type ligands. Coordination of 5 to [PtCl ₂(PEt₃)] gives two cis and two trans complexes [PtCl ₂(PEt₃)5] wherein rotation about the phospholyl-naphthyl vector is slow.
