Abstract: Bis(2-hydroxy-1-naphthyl)methane reacts with chlorodiphenylphosphine to afford the bis(phosphinite), Ph2P{(-OC10H6)(-CH2)(C10H6O-)}PPh2 (1) in good yield. The bis( phosphinite) 1 reacts with elemental sulfur or selenium to give the corresponding disulfide or diselenide; the structure of the selenium derivative, Ph2P(Se)-{(-OC10H6)(mu-CH2)(C10H6O-)} P(Se)Ph-2 (3) is confirmed by X-ray crystal structure analysis. Treatment of the ligand 1 with platinum metal derivatives results in the formation of ten-membered chelate complexes with the ligand showing an eta(2)-mode of coordination. The elucidation of the structures of the products is based on NMR (H-1 and P-31) spectroscopic data. Molecular structures of [CpRuCl{eta(2) -Ph2P{(-OC10H6)(mu-CH2)(C10H6O-)}PPh2-kappaP,kappaP}] (4) and [PtCl2{eta(2)-Ph2P{(-OC10H6)(mu-CH2)(C10H6O-)}PPh2-kappaP,kappaP}] (7) are determined by single crystal X-ray studies.
