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. ... Carbonylation reactions using transition metals are of con- ... PtC12(PPh3)2-Et3N system required 20-30 kg cm-1 of CO at ... Recent developments in hypervalent iodine chemistry have ... 1-halogenoalkynes4 without reduction of the ...
