Suzuki-Miyaura coupling of aryl tosylates and mesylates in water
Pschierer, Jan,Plenio, Herbert
, p. 2934 - 2937 (2010)
The palladium complex (0.5 mol-%) of a water-soluble sulfonated fluorenylphosphane (cataCXium Fsulf) enables the facile Suzuki-Miyaura coupling of various (heterocyclic) aryl tosylates and aryl mesylate with various (heterocyclic) boronic acids in excellent yields (> 95%) using water as the reaction solvent.
