✦ Synopsis

A new route to polymer-supported cyclopentadienes using nickelocene as a source of cyclopentadiene is discussed. Nickelocene reacts directly with polymer-supported trityl chloride to yield the cyclopentadiene substituted analogue. With both Merrifield's resin and a PEG based bromo-functionalised resin the cyclopentadiene substituted analogues are formed on reaction of the iodide form of the resin with nickelocene in the presence of triphenylphosphine.

A three-step preparation of a polymer-supported IBX reagent from poly(p-methylstyrene) is reported. This reagent has been used successfully for the efficient oxidation of a series of alcohols to the corresponding aldehydes.
