The Chemoselective, Enantiospecific Cross-Coupling of Secondary Boronic Esters and the Stability of Mesoporous Silica Supports for Pd Catalysis
(2011-09-19)
The Suzuki-Miyaura Cross-Coupling of aryl halides and aryl boronic esters has become one of the most important and oft used C-C bond forming reactions in industry and academia alike. Recently, substantial effort has been ...
Investigations of Novel Uses for Boron Compounds in Organic and Inorganic Chemistry
(2011-09-30)
Herein I describe a model study to determine the feasibility of organic hydride donors as a source of hydride in the regeneration of ammonia borane. Hydride transfer was observed in the model system comprised of Hantzsch ...
Enantiospecific, Regioselective Suzuki-Miyaura Cross-Couplings of Secondary, Allylic Boronic Esters
(2013-11-14)
The stereochemical course of the Pd–catalyzed Suzuki-Miyaura cross-coupling of α-substituted, enantioenriched allylic boronic esters with phenyl iodide has been examined. The secondary boronic esters were prepared in both ...
Highly Selective Rhodium-Catalyzed C-H Borylations in Preparation of Substrates for Suzuki-Miyaura Cross-Couplings: Mono- and Chemoselective Formation of Aromatic Compounds
(2015-03-27)
The advent of the Suzuki–Miyaura cross–coupling reaction and its significance to the synthesis of new carbon–carbon bonds has increased the demand for efficient routes to organoboron starting materials. C–H borylation ...
Investigations of a New and Improved Precataylst for Palladium Catalyzed Cross Coupling Reactions
(2013-07-02)
Little attention has been given to the formation of the putative PdL2
species required for Pd-catalyzed cross-coupling reactions. Active species are
generally difficult to store due to air-sensitivity and are therefore ...
Investigations Into Cross-Coupling of Secondary Organoboronic Esters
(2010-09-23)
Until recently, secondary organoboronic esters were not viable substrates in the Suzuki-Miyaura cross-coupling reaction; however under recently reported conditions from the Crudden group1, which includes the addition of ...
