Biaryl phosphane ligands in palladium-catalyzed amination.
Angew. Chem. Int. Ed. Engl. 47 , 6338, (2008) 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... |

Acid, silver, and solvent-free gold-catalyzed hydrophenoxylation of internal alkynes.
Beilstein J. Org. Chem. 9 , 2002-8, (2013) A range of arylgold compounds have been synthesized and investigated as single-component catalysts for the hydrophenoxylation of unactivated internal alkynes. Both carbene and phosphine-ligated compounds were screened as part of this work, and the most effici... |

Suzuki-Miyaura Cross-Coupling of Benzylic Bromides Under Microwave Conditions.
Tetrahedron Lett. 52(43) , 5656-5658, (2011) A procedure for benzylic Suzuki-Miyaura cross-coupling under microwave conditions has been developed. These conditions allowed for heterocyclic compounds to be coupled. Optimum conditions found were Pd(OAc)(2), JohnPhos as the catalyst and ligand, potassium c... |
