Biaryl phosphane ligands in palladium-catalyzed amination.

David S Surry et al.

Angewandte Chemie (International ed. in English), 47(34), 6338-6361 (2008-07-30)

Palladium-catalyzed amination reactions of aryl halides have undergone rapid development in the last 12 years, largely driven by the implementation of new classes of ligands. Biaryl phosphanes have proven to provide especially active catalysts in this context. This Review discusses

Suzuki-Miyaura coupling of NHC-boranes: a new addition to the C-C coupling toolbox.

Julien Monot et al.

Organic letters, 11(21), 4914-4917 (2009-10-06)

Complexes of triaryl- and trialkylboranes with N-heterocyclic carbenes (NHCs) participate in Suzuki-Miyaura cross-coupling reactions and provide coupled products in good yields under base-free conditions. The reaction can be applied to Csp(2)-Csp(2) and Csp(2)-Csp(3) carbon-carbon bond formation with triflates, iodides, bromides

Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions employing dialkylbiaryl phosphine ligands.

Ruben Martin et al.

Accounts of chemical research, 41(11), 1461-1473 (2008-07-16)

The cores of many types of polymers, ligands, natural products, and pharmaceuticals contain biaryl or substituted aromatic structures, and efficient methods of synthesizing these structures are crucial to the work of a broad spectrum of organic chemists. Recently, Pd-catalyzed carbon-carbon

Dialkylbiaryl Phosphines in Pd-Catalyzed Amination: A User's Guide.

David S Surry et al.

Chemical science, 2(1), 27-50 (2011-01-01)

Dialkylbiaryl phosphines are a valuable class of ligand for Pd-catalyzed amination reactions and have been applied in a range of contexts. This review attempts to aid the reader in the selection of the best choice of reaction conditions and ligand

Tetrahedron Letters, 47, 5143-5143 (2006)

Palladium-catalyzed Negishi a-arylation of alkylsulfones.

Zhou G, et al.

Tetrahedron Letters, 51(6), 939-941 (2010)

Palladium-Catalyzed Stille Cross-Coupling Reaction of Aryl Chlorides using a Pre-Milled Palladium Acetate and XPhos Catalyst System.

Advanced Synthesis & Catalysis, 350(7-8), 957-961 (2008)

Xphos ligand and platinum catalysts: A versatile catalyst for the synthesis of functionalized ?-(E)-vinylsilanes from terminal alkynes.

Hamze A, et al.

Journal of Organometallic Chemistry, 693(16), 2789-2797 (2008)

Synthesis of C-15 vindoline analogues by palladium-catalyzed cross-coupling reactions.

Peter D Johnson et al.

The Journal of organic chemistry, 71(20), 7899-7902 (2006-09-26)

Described are general protocols for the rapid construction of various C-15-substituted analogues of vindoline using palladium-catalyzed cross-coupling reactions. The required bromo- and iodovindolines were prepared in high yield by the reaction of vindoline with N-bromosuccinimide or N-iodosuccinimide, respectively. The study

Palladium-catalyzed, modular synthesis of highly functionalized indoles and tryptophans by direct annulation of substituted o-haloanilines and aldehydes.

Yanxing Jia et al.

The Journal of organic chemistry, 71(20), 7826-7834 (2006-09-26)

One-pot synthesis of indoles by a palladium-catalyzed annulation of ortho-haloanilines and aldehydes has been developed. Coupling of ortho-iodoaniline with aldehyde is realized under mild ligandless conditions [Pd(OAc)2, DABCO, DMF, 85 degrees C], whereas X-Phos is found to be the ligand

Palladium-catalyzed borylation of aryl chlorides: scope, applications, and computational studies.

Kelvin L Billingsley et al.

Angewandte Chemie (International ed. in English), 46(28), 5359-5363 (2007-06-15)
