    Abstract

    A new aryldichlorophosphine, 2-thioanisyldichlorophosphine, and its anisyl analogue, 2-anisyldichlorophosphine, were prepared by using an organozinc halide reagent of 2-thioanisole or 2-anisole with ethereal solution of PCl3 in refluxing conditions. From these aryldichlorophosphines, eight new multidentate phosphine ligands containing 2-thioanisyl, 4-thioanisyl, 2-anisyl, 1-naphthyl and 9-anthracenyl groups were synthesized and characterized. Characterization was based mainly on NMR spectroscopy and X-ray crystallography. The crystal structures of six ligands are reported. The electronic effects on basicity of ligands
    are discussed.
