α,α-Disubstituted propargylic alcohols were transformed into enones by the catalysis with Ag(I) or Ag(I)–Me3SiCl under the mild conditions. This procedure provides a new synthetic method of α,β-unsaturated ketones having an oxygen function at α′ position from 2-butyne-1,4-diol derivatives. 3-Acetoxy-1,4,4-triphenyl-3-buten-2-one was obtained from 4-acetoxy-1,1,4-triphenyl-2-butyn-1-ol by the catalysis with tin(IV) chloride or aluminium chloride.
