Aqueous-Phase, Palladium-Catalyzed Cross-Coupling of Aryl Bromides under
Conditions, Using Water-Soluble, Sterically Demanding Alkylphosphines.
12- 096 Mild
— Water-soluble phosphines (I) are found to be efficient ligands in palladium-catalyzed Suzuki, Sonogashira, and Heck coupling reactions of aryl bromides (29 examples). A biphasic system water/toluene, 50% aqueous MeCN, or water alone can be
used as solvent. Notably, Suzuki coupling of hydrophilic aryl bromides like compounds
(II) gives high yields without using organic solvents for the reaction or purification.
