An Unusual Example of Base-Free Catalyzed Reduction of C═O and C═NR Bonds by Transfer Hydrogenation and Some Useful Implications
(American Chemical Society, 2008-03)
A series of Cp*IrIII(NHC) complexes have been used in the catalytic transfer hydrogenation of ketones and imines in iPrOH, showing that the reduction of ketones is complete within minutes at room temperature, with the ...
pH-Tunable Hydrogelators for Water Purification: Structural Optimisation and Evaluation
(Wiley, 2012-02)
A focused library of potential hydrogelators each containing two substituted aromatic residues separated by a urea or thiourea linkage have been synthesised and characterized. Six of these novel compounds are highly efficient ...
Iridium NHC based catalysts for transfer hydrogenation processes using glycerol as solvent and hydrogen donor
(American Chemical Society, 2011-10)
A series of iridium and ruthenium N-heterocyclic carbene based catalysts of general formula [IrI2(AcO)(bis-NHC)] or [Ru(η6-arene)(NHC)CO3] have been tested in the reduction of several organic carbonyl compounds using ...
A Y-Shaped tris-N-heterocyclic carbene for the synthesis of simultaneously chelate-monodentate dipalladium complexes
(American Chemical Society, 2011-11)
A Y-shaped tris-NHC ligand has been obtained and coordinated to palladium, affording metal complexes with novel topological properties. The tris-NHC ligand is capable of coordinating the two metals, affording two different ...
Stereoselective Synthesis of the Cytotoxic 14-Membered Macrolide Aspergillide A
(American Chemical Society, 2010)
A stereoselective synthesis of the cytotoxic 14-membered macrolide aspergillide A has been performed. The preparation of a cis-2,6-disubstituted tetrahydropyran ring via stereoselective reduction of an intermediate cyclic ...
Double diastereoselection in anti aldol reactions mediated by dicyclohexylchloroborane between an L-erythrulose derivative and chiral aldehydes
(Royal Society of Chemistry, 2012)
Anti aldol reactions of an L-erythrulose derivative with several α-chiral aldehydes mediated by
dicyclohexylboron chloride are examined. Good yields and stereoselectivities are observed. The results
are best explained ...
Photocatalysts in ceramics
(DKG Deutsche Keramische Gesellschaft, 2012)
Advanced oxidation processes
(AOPs) are oxidation processes
based on sufficient concentrations of
hydroxyl radicals to degrade dissolved organic compounds present
in water or those that are dispersed
in air to mineral ...
Stereoselective chemoenzymatic synthesis of enantiopure 2-(1H-imidazol-yl)cycloalkanols under continuous flow conditions
(American Chemical Society, 2012-07)
The development of continuous flow processes for the synthesis of chiral enantiopure 1-(2-hydroxycycloalkyl)imidazoles is reported. For the ring-opening reaction microwave batch processes and continuous flow reactions have ...
Intramolecular oxidation of the alcohol functionalities in hydroxyalkyl-n-heterocyclic carbene complexes of iridium and rhodium
(WILEY-VCH Verlag, 2011-08-04)
A series of hydroxyalkyl-functionalized imidazolium salts have been coordinated to Rh and Ir to afford the corresponding MCp*–(NHC) (Cp*=pentamethylcyclopentadienyl) complexes. The reactivity of the new complexes has been ...
Diamine acylation with amino acid derivatives: an example of proximity effect in organic reactivity induced by supramolecular aggregation
(Elsevier, 2015-02)
Unexpected high yields of diamide 3 are obtained in the reaction of 1,3-propanediamine with an activated ester of l-valine (1) under adverse proportions of the reactants, namely in the presence of an excess of 1,3-propanediamine. ...
