[BMI][PF(6)] has been supported on silica and alumina in order to study the effect of these classical oxide supports on the structure of the ionic liquid. A widespread characterization by TGA, DSC, XRD and solid NMR of thin films of [BMI][PF(6)] immobilized on these amorphous supports has evidenced a dramatic effect on the ionic liquid structure depending(More)
The use of efficient Pd systems bearing C(2)-symmetric chiral diphosphite ligands derived from carbohydrates in asymmetric allylic substitution reactions is described here, reaching TOFs > 22 000 h(-1) in allylic alkylation and ca. 400 h(-1) in allylic amination, giving excellent enantioselectivities (ee > 99%) and kinetic resolution of the racemic(More)
This Minireview considers the foremost reported works involving glycerol as a solvent in the synthesis of organometallic complexes and metallic nanoparticles. This analysis highlights their catalytic applications. A special emphasis is devoted to the ability of glycerol to immobilize nanometric species, which, in turn, enables an efficient recycling of the(More)
Thioether-phosphines, 1 and 2, were applied for the stabilisation of palladium nanoparticles (PdNPs) synthesised by a bottom-up methodology, using [Pd2(dba)3] as an organometallic precursor. For the phenyl containing ligand 1, small (d(mean) = 1.6 nm), well-defined and dispersed nanoparticles were obtained; however, ligand 2 involving a long alkyl chain led(More)
The hybrid imine/amine palladium(II) coordination complexes [PdX2(kappa2-N(imino),N(amino))](X = Cl, AcO; kappa2-N(imino),N(amino)= 4ClC6H4CHNCH2(CH2)nN(CH3)2, n= 1, 2) have been prepared in different isomeric forms which include E/Z arrangement around the C[double bond]N bond of the hybrid ligand and {Pd(kappa(2)-N(imino),N(amino))} ring conformation. The(More)
Chiral carbohydrate-based diphosphites were used for Pd-catalysed asymmetric allylic substitution (alkylation, amination, phosphination) in neat ionic liquids (ILs). Pyrrolidinium-based IL led to the best activities, allowing an efficient catalyst immobilization. In the allylic amination (TOF > 3100 h(-1)), the catalyst could be recycled nine times(More)
The ortho-metallation reaction of chloro and acetato complexes of palladium(ii) having 5- and 6-membered kappa(2)-(N(amino),N(imino)) chelate ligands, [Pd(Me(2)NCH(2)(CH(2))(n)NCH(4-ClC(6)H(4)))(X)(2)] (X = AcO, Cl; n = 1, 2), in methanol solution has been carried out. The results are a good indicator of the distinct nature of the transition state involved(More)
New catalytic systems based on in situ and preformed palladium nanoparticles in ionic liquids (characterised by TEM) starting from palladium acetate or dipalladiumtris(dibenzylideneacetone) have been applied in the synthesis of 4-phenylbutan-2-one (II), a model compound for the preparation of fragrances. Imidazolium-based ionic liquid containing a methyl(More)
