Phosphine dendrimer-stabilized palladium nanoparticles, a highly active and recyclable catalyst for the Suzuki-Miyaura reaction and hydrogenation.

[reaction: see text] Phosphine dendrimer-stabilized palladium nanoparticles were synthesized and found to be highly effective for Suzuki coupling reactions, affording good to excellent product yields, high turnover number (up to 65,000), and excellent reusability (up to 9 catalytic runs). Furthermore, these Pd nanoparticles are efficient and selective catalysts for hydrogenations.

Thermomorphic system with non-fluorous phase-tagged Ru(BINAP) catalyst: facile liquid/solid catalyst separation and application in asymmetric hydrogenation.

The thermomorphic BINAP derivative 1 tagged with long alkyl chains was prepared from (S)-5,5'-diamino BINAP and applied to Ru-catalyzed asymmetric hydrogenation of beta-ketoesters under homogeneous conditions in 3:1 (v/v) ethanol/1,4-dioxane at 60 degrees C with high enantioselectivity (up to 98% ee). Results indicated that the Ru(1) catalyst was easily recovered by simple cooling and precipitation and could be used for at least four cycles without any loss of enantioselectivity.

Phase selectively soluble dendrimer-bound osmium complex: a highly effective and easily recyclable catalyst for olefin dihydroxylation.

A new switched biphasic catalysis system for highly effective olefin dihydroxylation has been described, in which the dendritic osmium catalyst preferred to dissolve in the non-polar organic layer and could be easily separated from the polar diol products through phase separation induced by addition of water at the end of the reaction.
