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/Sonogash

A protecting group Ph(O) for terminal ethyne was newly developed. This protecting group can be introduced readily to terminal ethyne by CuI-catalyzed phosphination and subsequent oxidation with H Ph(O)-protected ethynes remained intact in Sonogashira coup
