A four-step synthesis to aryl etherderivatives, three of which utilize polymer-supported reagents, has been developed. Supported triphenylphosphine was successfully utilized in two distinct synthetic processes in the first step, whilst supported base and ionic and covalent scavengers were employed to complete the synthesis and purification of the target compounds.
