โฆ Synopsis
Optimum conditions for the preparation of aryl-alkyl ethers from N-protected aminoalcohols using polymer-supported triphenylphosphine have been developed. In contrast to previous literature reports, it was discovered that the progress of this reaction is greatly improved when a tertiary amine base is employed, along with minor modifications being made to the order of reagent addition.

Polymer supported 1, 5, .0]dec-5-ene (PTBD) was used as a base and a reagent scavenger for rapid synthesis of aryl ethers from phenols and alkyl or aryl halides. This method provides a simple reaction operation, and generally high purity of reaction product in good yield.
The synthesis of aryl ethers from phenols and alcohols using polymer-bound triphenylphosphine and diethyl azodicarboxylate (DEAD) is described. The polymer-bound triphenylphosphines are easily removed by filtration from the reaction products. This method is operationally simple and provides the prod
