  Preparation and Reaction of Quinolinyl (or Pyridinyl)phosphonium Salts with Base and Pivalaldehyde

  摘要：

  alpha- and gamma-Heteroaryltriphenylphosphonium iodides were prepared by reaction of the corresponding heteroaryl iodides with triphenylphosphine. Reaction of beta-heteroaryl iodides with triphenylphosphine in the presence of a palladium catalyst gave beta-heteroaryltriphenylphosphonium iodides. Elimination of the heteroaryl group was achieved by treating the heteroaryltriphenylphosphonium iodides with a base. Further, the heteroaryl group was trapped with pivalaldehyde to introduce a pivaloyl substituent onto the heteroaromatic ring.

  Chemistry of Heteroaryltriphenylphosphonium Iodides: Preparation from Iodoheteroaromatics and Elimination of the Phosphonium Iodide Group Using Basic Solvents

  摘要：

  alpha- and gamma-lodoheteroaromatics were found to react with triphenylphosphine to give heteroaromatictriphenylphosphonium iodides in excellent yields. beta-lodoheteroaromatics, which are less reactive with triphenylphosphine compared to alpha- or gamma-compounds, were converted into the corresponding phosphonium iodides using palladium catalysts. Treatment of heteroaromatictriphenylphosphonium iodides resulted in the elimination of the phosphonium iodide group using basic solvents such as aqueous sodium hydroxide or ethanol - triethylamine.
