Al(OTf)3: an efficient recyclable catalyst for direct nucleophilic substitution of the hydroxy group of propargylic alcohols with carbon- and heteroatom-centered nucleophiles to construct C–C, C–O, C–N and C–S bonds
A general and highly efficient Al(OTf)3-catalyzed methodology has been developed for the direct nucleophilic substitution of the hydroxygroup in propargylic alcohols with a variety of carbon- and heteroatom-centered nucleophiles such as alcohols, aromatic compounds, amides, and thiols, leading to the construction of C–C, C–O, C–N and C–S bonds.

The silver-catalyzed alkynyl borrowing amination of secondary propargyl alcohols via C(sp3)–C(sp) bond cleavage has been developed. This new strategy was based on the β-alkynyl elimination of propargyl alcohols and alkynyl as the borrowing subject. This alkynyl borrowing amination featured high atom economy, wide functional group tolerance, and high efficiency.
