Inverse phase-transfer catalysis by cyclodextrins. Palladium-catalyzed reduction of bromoanisoles with sodium formate

Article abstract of DOI:10.1246/bcsj.63.176

Bromoanisoles have been reduced to hydrocarbons with sodium formate in high yields under mild conditions using palladium on charcoal and cyclodextrins as catalysts. In aqueous phase-organic phase reactions employing a solid-phase catalyst (Pd/C), cyclodextrins function as inverse phase-transfer catalysts which transfer the substrate into the aqueous phase.
