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

Boron podands 1–4 (B-podands) were studied as strong complexing agents of alkali metal cations and very powerful catalysts in typical anion promoted reactions under solid–liquid conditions, even in chlorobenzene and acetonitrile. The results were

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

Silicon podands (1–10) were synthesised and their complexation reaction of Na+ cations were studied by calorimetric and PM5 theoretical methods. Both methods provide evidence for formation of the respective complexes with Na+ cations of different s

The use of aliphatic esters, ethers and ketones such as dimethyl carbonate (DMC), methyl-tert-amyl ether (MTAE), 5-methyl-2-hexanone (MIAK), 4-methyl-2-pentanone (MIBK) as an alternative to traditional solvents (toluene, chlorobenzene, etc.) was expl

The regiochemical outcome of nucleophilic substitution reactions of PNP16C6 (1) by a series of alkaline-earth metal p-nitrophenoxides (6–8) in chlorobenzene–solid salt two-phase systems strongly depends on the identity of the metal ion M2+ (Ca2+,

A systematic study on the use of liposoluble PEG5000Bu3N+Br- (1a) as the catalyst in a series of anion-promoted reactions carried out under both liquid−liquid (LL) and solid−liquid (SL) phase-transfer catalysis (PTC) conditions is reported. A com
