Molecular volcano plots, a tool generally used to identify ideal catalysts for a given chemical transformation, are employed in an alternative fashion to examine the substrate scope by revealing the range of substrates that can be accommodated by a single ...
In the presence of a catalytic amount of Pd(TFA)2 and a chiral Pyox ligand under oxygen atmosphere, oxidative Heck reaction between arylboronic acids and 4- substituted or 4,4-disubstituted cyclopent-1-enes afforded the chiral arylated products with concur ...
Carbosilylation of alkenes can be an efficient approach to the synthesis of organosilicon compounds. However, few general methods of carbosilylation are known. Here, we introduce a strategy for arylsilylation of electron deficient terminal alkenes by combi ...
This thesis focuses on the design and the synthesis of mono- and dinuclear iron clathrochelate complexes and their applications in materials science.
Dinuclear iron clathrochelate complexes can be synthesized in different oxidation states: i. as negative ...
This work is addressed to the phenomenon of catalyst deactivation taking place during the repeated uses in the reaction of Suzuki-Miyaura (S-M) cross-coupling, which is widely applied in industry for C-C bond formation. Ligandless catalysts based on Pd(0) ...
This paper describes the synthesis of Pd-containing catalysts based on nonfunctionalized hypercrosslinked polystyrene via impregnation with Pd acetate. Developed Pd nanoparticulate catalyst allowed achieving conversion of aryl halide up to 90% in Suzuki cr ...
CONSPECTUS: Ligand development plays an essential role in the advance of homogeneous catalysis. Tridentate, meridionally coordinating ligands, commonly termed pincer ligands, have been established as a privileged class of ligands in catalysis because they ...
Asymmetric metal-catalyzed C-H functionalization has enjoyed great success as a powerful strategy for the rapid construction of elaborate structures from simple precursors. For example, aryl (pseudo)halides have been extensively employed as electrophilic s ...
Here we show that a scaffold combining siloxide ligands and a bridging oxide allows the synthesis and characterization of the stable dinuclear uranium(IV) hydride complex [K-2{U(OSi((OBu)-Bu-t)(3))(3)(mu-O)(mu-H)(2)}], 2, which displays high reductive ...
In this study, a manganese(IV) oxide-mediator (MnO2-mediator) system for the abatement of sulfonamide antibiotics was evaluated. Two simple model humic constituents, syringaldehyde (SA) and acetosyringone (AS), could promote the transformation of sulfonami ...
