Abstract

Together with a strongly oxidizing polyoxometalate, H5PV2Mo10O40, PtII(N-(2,6-diisopropylphenyl)pyrazin-2-ylmethanimine)Cl2 forms a combined catalyst that was active in the tandem pinacol coupling-rearrangement of aryl aldehydes to give mostly the corresponding diarylacetaldehyde in high yields using molecular hydrogen as the reducing agent.
