Recyclable catalysts for palladium-catalyzed C - O coupling reactions, Buchwald-Hartwig aminations, and Sonogashira reactions

Abstract

Simply reuse: Homogeneous palladium catalysts are effective and attractive tools for advanced organic synthesis (see example). Compound 1 belongs to a new class of ligands that enable recycling of the precious-metal catalyst directly from the reaction without any heterogenization. © 2010 WILEY-VCH Verlag GmbH & Co.
