Bimetallic Ru-Ni and Rh-Ni nanoparticles coated with a phase transfer agent are efficient catalysts for the hydrogenolysis of aryl ether C-O linkages in water. For dimeric substrates with weaker C-O linkages, i.e. a-O-4 and b-O-4 bonds, low loadings of the precious metal in the bimetallic alloy quantitatively afford monomers, whereas for the stronger 4-O-5 linkage higher amounts of the precious metal are required to achieve complete conversion. Under the optimized, relatively mild operating conditions, the C-O bonds in a range of substituted ether compounds are efficiently cleaved. Mechanistic insights into the reaction pathways are provided.
