In situ generation of water-stable and -soluble ruthenium complexes of pyridine-based chelate-ligands and their use for the hydrodeoxygenation of biomass-related substrates in aqueous acidic medium
The complexes [Ru(2,2?-dipicolylamine)(OH2)3](OTf)2 and [Ru(6,6?-bis(aminomethyl)-2,2?-bipyridine)(OH2)2](OTf)2 can be prepared by reaction of 2,2?-dipicolylamine or 6,6?-bis(aminomethyl)-2,2?-bipyridine with [RuIII(DMF)6](OTf)3 in aqueous medium. During the reaction an in situ reduction from a paramagnetic RuIII to a diamagnetic RuII-complexes occurs with one equivalent of DMF acting as the reducing agent for two ruthenium centres by its reaction with water and decomposition to dimethylammonium triflate and CO2 generating an additional equivalent of HOTf in the process. The complex solutions are active as catalysts for the hydrogenation of 2,5-hexanedione and 2,5-dimethylfuran to 2,5-hexanediol and 2,5-dimethyltetrahydrofuran with both complexes realizing very high yields (>95% combined yield of the two products with the selectivity determined as a function of added acid co-catalyst). The 2,2?-dipicolylamine complex is stable to 150?C, while the 6,6?-bis(aminomethyl)-2,2?-bipyridine complex is stable to 200?C allowing the in situ hydrolysis of 2,5-dimethylfuran to the 2,5-hexanedione and thus direct conversion to the same products in up to 78% combined yield. The effects of co-solvents, acid co-catalysts and temperature on catalyst activity, decomposition and stability are explored.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, COA of Formula: CF3NaO3S, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 2926-30-9
