A novel solid-phase self-organized catalyst of palladium nanoparticles was prepared from PdCl2 with main-chain viologen polymers via complexation and reduction. This insoluble nanocatalyst nano-Pd-V efficiently promoted α-alkylation of ketones with primary alcohols in the presence of Ba(OH)2·H2O under atmospheric conditions without organic solvents. The nano-Pd-V catalyst was reused without loss of catalytic activity.
Alcohols for the α-alkylation of methyl ketones and indirect aza-wittig reaction promoted by nickel nanoparticles

Nickel nanoparticles have been found to activate primary alcohols used for the α-alkylation of ketones or in indirect aza-Wittig reactions. These processes involve hydrogen transfer from the alcohol to the intermediate α,β-unsaturated ketone or imine, respectively. All these reactions are carried out in the absence of any ligand, hydrogen acceptor or base under mild reaction conditions. For the first time nickel is employed as a potential alternative to noble-metal-based catalysts in both reactions. A reaction mechanism is proposed on the basis of some deuteration experiments.

A one-pot process for the enantioselective preparation of saturated secondary alcohols from propargyl ketones under hydrogen transfer conditions
Bogliotti, Nicolas,Dalko, Peter I.,Cossy, Janine
, p. 6915 - 6918 (2007/10/03)
Propargyl ketones can be directly transformed to enantio-enriched saturated secondary alcohols in a one-pot reaction using chiral RuCl[N-(tosyl)-1,2- diphenylethylenediamine)(p-cymene) and Pd/BaSO4 as catalysts, under transfer hydrogenation con
