Abstract

For the development of new catalysts for the dehydrogenation of iso-propanol various nitrogen containing ligands have been screened with [RuCl2(p-cymene)]2 as Ruthenium precursor. Some of these in situ prepared catalysts show a comparably high activity as our previously investigated RuCl3 · x H2O / phosphine systems especially applying tertiary amines like TMEDA as ligands. Under our standard reaction conditions turnover frequencies over 300 h-1 after 2 hours have been obtained. By tuning of the substrate to catalyst ratio for both systems, RuCl3 · x H2O / phosphine as well as [RuCl2(p-cymene)]2 / TMEDA, a further increase of the catalyst activity has been achieved. Thus at comparably low temperature (90°C) unprecedented catalyst activities, turnover frequencies up to 500 h-1 after 2 h for [RuCl2(p-cymene)]2 / TMEDA and up to 700 h-1 for RuCl3 · x H2O / 2-diadamantylphosphinyl-1-phenyl-1H-pyrrole are obtained.
