Abstract

A high loading polymer supported amine N-oxide has been prepared and shown to be a good, practicable, and readily recyclable promoter of the Pauson-Khand reaction under mild conditions, generally affording excellent yields of cyclopentenones. In addition, use of N-phenylsulfonyl oxaziridine as a co-oxidant allows use of reduced quantities of the readily available parent polymer-supported amine without the need for prior oxidation of the resin.
