[Selective metalation and solid phase organometallic chemistry].
Recently, solid-phase synthesis has been recognized as an important methodology for combinatorial chemistry or automated synthesis directed at drug discovery. Various synthetic methodologies have been applied to solid-phase synthesis, although it appears that organometallic chemistry in this area is still being explored. In solution-phase chemistry, organometallic reagents have been utilized fo...
متن کاملEmployment of Palladium Pincer Complex Catalysts and Lewis Acids for Synthesis and Transformation of Organometallic Compounds
This thesis is mainly focused on the development of new palladium catalyzed transformations using so-called “pincer” complexes. These complexes were applied as catalysts in two important areas of organometallic chemistry: substitution of propargylic substrates by dimetallic reagents; and allylation of aldehydes and imines by allylstannanes. In addition, this thesis includes studies on Lewis aci...
متن کاملNew synthetic transformations via organoboron compounds
It was previously reported that the palladium-catalyzed cross-coupling reaction of 1-alkenylboron compounds with various vinylic or aryl halides in the presence of base provides the corresponding coupling products in high yields, stereoand regioselectively. The recent progress of such reactions, including the reaction of sterically hindered arylboronic acids with sterically hindered haloarenes,...
متن کاملCobalt-Catalyzed Cross-Coupling Reactions of Aryl Halides
Transition metal-catalyzed C–C cross-coupling reactions are among the most powerful transformations known to organic chemists, and have received considerable attention over the last decades. For this reason, the development of mild chemo-, regio-, and stereoselective syntheses for the formation of carbon–carbon bonds catalyzed by metal complexes is of great interest. These methods have had a pr...
متن کاملConfigurationally stable, enantioenriched organometallic nucleophiles in stereospecific Pd-catalyzed cross-coupling reactions: an alternative approach to asymmetric synthesis
Several research groups have recently developed methods to employ configurationally stable, enantioenriched organometallic nucleophiles in stereospecific Pd-catalyzed cross-coupling reactions. By establishing the absolute configuration of a chiral alkyltin or alkylboron nucleophile prior to its use in cross-coupling reactions, new stereogenic centers may be rapidly and reliably generated with p...
