sulfide-promoted, microwave-assisted Pauson-Khandreaction has enabled the formation of fused cyclopentenones using sub-stoichiometric quantities of a cobalt mediator over rapid reaction times and with no requirement for an external source of toxic carbon monoxide gas. This protocol displays applicability to both intra- and intermolecular Pauson-Khandreaction examples.

A readily prepared polymer-supported alkyl methylsulfide has been shown to be a recyclable, practically convenient, and efficient promoter of the Khand cyclisation reaction, affording good to excellent yields of cyclopentenones.
