Imidazolium-based ionic liquids (ILs) containing ester moieties in the side chain were successfully used as an alternative to traditional ILs in the Beckmann rearrangement of ketoximes catalyzed by 2,4,6-trichloro[1,3,5]triazine. The procedure is mil

The triplet N,N-dimethylaminophenyl cation, a highly reactive but chemospecific electrophile, has been used as a probe for characterizing the properties of reaction media for a series of imidazolium ILs. With the N-hexyl-N-methyl imidazolium derivati

Metal ion electrophilic catalysis (Li + > Na + K + ) has been found in ring-opening reactions of 1,2-epoxides 1-5 by metal halides MHal in ionic liquids. The results have been rationalized on the basis of a transition state where the cation M + stabi

N-(2-Nitro-benzenesulfonyl) activated L-tyrosine methyl ester has been directly N-alkylated under solid-liquid phase-transfer catalysis (SL-PTC) conditions and in a coordinating non-hydrogen bonding donor (non-HBD) solvent, which reduces through spec

The oxirane ring of 3-alkyl- and 3-arylglycidic esters has been opened with trifluoromethanesulfonamide (TfNH 2 ) under solid-liquid heterogeneous conditions. The corresponding α-hydroxy-β-triflamido esters were produced in good yields, in a regio-

Symmetric and non-symmetric 2,6-disubstituted morpholines were synthesized through regioselective nucleophilic ring opening of oxiranes with tosylamide under solid–liquid phase transfer catalysis (SL-PTC) conditions followed by cyclization of the t
