title: Unexpected multifunctional effects of methylated cyclodextrins in a palladium charcoal-catalyzed Suzuki-Miyaura reaction.
abstract: [reaction: see text] Native and modified cyclodextrins (CDs) have shown polyvalent properties in a biphasic Pd/C-catalyzed Suzuki-Miyaura reaction. In addition to their mass transfer ability, the CDs favored the dispersion of the catalyst in water. With the randomly methylated CDs (RaMe-beta-CD), the gains of initial activities were multiplied by factors between 3.8 and 343 depending on the nature of the substrates. The reusability of the system was also demonstrated.
