Application

Aluminum trifluoromethanesulfonate (aluminum triflate or Al(OTf)3) can be employed as a catalyst:
  • In the regioselective synthesis of cyclic ethers by cycloisomerization of unsaturated alcohols.
  • In the conversion of saccharides into 5-hydroxymethylfurfural (5-HMF).
  • Along with Pd(OAc)2/BINAP for the methoxycarbonylation reaction of phenylacetylene.

Accessing enantiomerically enriched amines often demands oxidation-state adjustments, protection and deprotection processes, and purification procedures that increase cost and waste, limiting applicability. When diastereomers can be formed, one isomer is attainable. Here, we show that nitriles, largely viewed as insufficiently

An unexpected silver triflate-catalyzed tandem reaction of N'-(2-alkynylbenzylidene)hydrazide with ketene through 6-endo-cyclization, [3+2] cycloaddition and rearrangement is reported. This reaction proceeds efficiently to generate the molecular complexity with the formation of four bonds in a one-pot procedure.
