Rare earth metal trifluoromethanesulfonates (rare earth metal triflates, RE(OTf)3) were found to be efficient catalysts for Friedel-Crafts acylation and alkylation. In the presence of a catalytic amount of RE(OTf)3, acylation of aromatic compounds ha

Scandium trifluoromethanesulfonate is found to be a Lewis acid catalyst for selective cleavage of esters containing a coordinative group adjacent to an ester moiety. The reaction proceeds under weak acidic conditions at room temperature; the catalyst

A synthesis of (1S,2R)-1-amino-2-indanol (1), a key component of an HIV protease inhibitor, was accomplished through (R)-2-hydroxy-1-indanone ((R)-3), which was prepared by an intramolecular Friedel–Crafts acylation of (R)-2-acetoxy-3-phenylpropano

The second-order optical nonlinearities and transparencies of seventeen 4,4′-disubstituted stilbenes and ten related compounds containing a trifluoromethyl group at the para position, as the electron-withdrawing group, were examined. The introducti

The Friedel-Crafts acylation of substituted benzenes proceeds smoothly by using a catalytic amount of a lanthanide trifluoromethanesulfonate [Ln(OTf)3], which is easily recovered from the reaction mixture and reused without a decrease in catalytic ac
