Origin of metallic-like behavior in disordered carbon nano-onions

Carbon nano-onions are a class of nanomaterials that can exhibit long electron spin relaxation times at room temperature and thus hold promise as potential building blocks for spintronics and quantum information processing devices. Despite first being synt ...

Structure-property relationships and mixed conductivity in layered hybrid perovskites based on phenyl-derived spacers

Algirdas Ducinskas

Hybrid halide perovskites are currently one of the most studied semiconductors. However, due to poor intrinsic and extrinsic stability, further developments to commercialize devices based on hybrid halide perovskites are limited. Many different strategies ...

Probing Substrate Scope with Molecular Volcanoes

Matthew Wodrich, Anne-Clémence Corminboeuf, Boodsarin Sawatlon

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 ...

"Palladium-Catalyzed Diamination of Alkynes in Synthesis of Tetracycles" and "Copper-Catalyzed Cyanoalkylation of Unactivated Alkenes"

Minh Tu Ha

The thesis deals with the development of transition metal-catalyzed difunctionalization of alkenes and alkynes, which can be categorized into two major topics: (1) palladium-catalyzed diamination of alkynes for the synthesis of tetracycles; (2) copper-cata ...

Organocatalysis: Fundamentals and Comparisons to Metal and Enzyme Catalysis

Pierre Vogel

Catalysis fulfills the promise that high-yielding chemical transformations will require little energy and produce no toxic waste. This message is carried by the study of the evolution of molecular catalysis of some of the most important reactions in organi ...

Functionalized Ionic (Poly)Styrenes and their Application as Catalysts in the Cycloaddition of CO2 to Epoxides

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Felix Daniel Bobbink, Shoubhik Das

Valorization of CO2, an abundant C(1) synthon, into platform chemicals is of growing interest. In this context, a key reaction is the cycloaddition of CO2 to epoxides to form carbonates (CCE). A series of organocatalysts for this reaction, based on imidazo ...

Olefin Hydrogenation with Single-Site Gold

Butene hydrogenation activity is intimately connected with the occupied and unoccupied electronic states of gold active site. We prepare well-defined Au(III) sites in IRMOF-3 structure, and tuned the metal density-of-states by replacing the substituent gro ...

A Mechanochemical Switch to Control Radical Intermediates

Ursula Röthlisberger, Elizabeth Claire Brunk

B-12-dependent enzymes employ radical species with exceptional prowess to catalyze some of the most chemically challenging, thermodynamically unfavorable reactions. However, dealing with highly reactive intermediates is an extremely demanding task, requiri ...

Enol Phosphinates and Phosphonates: Practical Electrophiles for Cross-Coupling Strategies

Tom Woods

Enol phosphinates and phosphonates can be readily prepared from simple lactams in high yields and are both stable and storable. Both these substrates can be employed successfully in homogeneous Suzuki-Miyaura and Stille cross-couplings protocols. Additiona ...

Rationalisation of solvent effects in the diels-alder reaction between cyclopentadiene and methyl acrylate in room temperature ionic liquids

Paul Joseph Dyson, Gabor Laurenczy, Ana Vidis

The Diels-Alder reaction between cyclopentadiene and methyl acrylate in ionic liquids has been studied in detail. The effect of contamination of the ionic liquids by common impurities, viz. sodium and chloride ions, and water, on the selectivity has been i ...
