Despite the ubiquity of metallic gold (Au) in popular culture, its deployment in homogeneous
catalysis has only recently undergone widespread investigation. In the past decade, and …

Charged intermediates and reagents are ubiquitous in organic transformations. The
interaction of these ionic species with chiral neutral, anionic, or cationic small molecules has …

The organic chemistry of polyvalent iodine compounds has experienced an unprecedented,
explosive development during the last decade of the 20th century. A quick SciFinder Scholar …

Supramolecular catalysis is a rapidly expanding discipline which has benefited from the
development of both homogeneous catalysis and supramolecular chemistry. The properties …

The synthetic uses of organicdiazo compounds for carbenoid transformations have
undergone a renais-sance in recent years as a result of the development of new transition …

Despite the tremendous advances of the past four decades, chemists are far from being able
to use chiral catalysts to control the stereoselectivity of any desired reaction. New concepts …

Aziridines are the nitrogen analogues of epoxides and exhibit similar reactivity patterns as
electrophilic reagents. 1 They undergo highly regio-and stereoselective transformations and …

Asymmetric catalysis with chiral metal complexes has received considerable attention in
recent years, and its contribution to the art of organic synthesis has become of leading …

Traditionally, transition metal–catalyzed enantioselective transformations rely on chiral
ligands tightly bound to the metal to induce asymmetric product distributions. Here we report …

The ion-pair concept1-4 was introduced in 1926 by Bjerrum5 to account for the behavior of
ionophores (species, such as alkali halides, that are ionic in the crystalline state and exist as …
