| Abstract: | Abstract The reactions of a variety of trico-ordinate phosphorus compounds, Ar n P(OR)3-n (n = 1 or 2), and cyclic analogues, with acrylonitrile, ethyl acrylate or ethyl phenylpropiolate and alcohols or phenols in low polarity media gives rise to a wide range of pentaco-ordinate phosphorus compounds. Attempts to extend this synthetic route to phosphoranes containing Psbnd]N or Psbnd]S bonds met with no success. |
