Abstract

Dichloro- and dihydridoruthenium(II) catalysts attached to an amphiphilic resin (PS−PEG) were prepared and tested for hydrogenation of supercritical carbon dioxide (scCO2) in the presence of dimethylamine leading to N,N-dimethylformamide (DMF). The supported catalysts were successfully recyclable with only moderate loss of activity.
