Abstract
Abstract Intermolecular Pauson-Khand (PK) reactions of norbornene-derived substrates have been carried out with several α,ω-alkynols under both normal homogeneous conditions and with the alkynol bound to functionalized Merrifield's polymer beads. With 2% crosslinked resin chemoselectivity favoring PK product formation over alkyne trimerization and other related side reactions is enhanced over that found either in solution or on 1% crosslinked polymer. Alkynol chain length and nature of the linker also significantly affect the outcome of the polymer-supported process.
