Me3Si-/Ph2P(O)-protected ethynes were successfully transformed to unsymmetrical arylethynes via a one-pot Ph2P(O)-deprotection/ [Pd(dppf)Cl2]-catalysed coupling and one-pot Me3Si-deprotection/Sonogashira coupling under mild conditions and in high yield. Unsymmetrical phenylethynes, unsymmetrical extended phenylene ethynylenes and unsymmetrical anthrylethynes were successfully synthesised in good to excellent yields.
