Non-Noyori-Type Ruthenium-POP Pincer Catalysts in Ethanol Upgrading
Butanol is one of the most promising candidates for replacing gasoline fuel in future grid-independent applications. In this study, we report the synthesis and analysis of new ruthenium-POP pincer complexes of the general formula [RuHCl(POP)(PPh3)] using commercially available or easy-to-synthesize tridentate POP pincer ligands, all derivatives of xantphos, DPEphos, (diphosphino)diethyl ether, and DBFphos. Their analytical properties were found to show clear trends in relation to the electronic and steric properties of the ruthenium center and ligand framework. We applied the complexes in the Guerbet-type upgrading of ethanol toward 1-butanol and higher linear alcohols, reaching up to 28% yield of 1-butanol at 120 °C for 48 h.
期刊介绍：
With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
