Mild palladium-catalysed carbonylation of alkynylphenyliodonium toluene-p-sulphonates under carbon monoxide at atmospheric pressure
Abstract
Alkoxycarbonylation of alkynylphenyliodonium toluene-p-sulphonates catalysed by a palladium catalyst proceeded under carbon monoxide at atmospheric pressure at room temperature to give alkyne carboxylates in high yields.
