Nanofiltration is a technique which can efficiently separate products from metals, and as well can preserve the activity of catalysts for reuse. This technique does have the disadvantage of specific molecular weight requirements for catalyst, but does not require additional reagents/scavengers. Another possible work-up option is to take advantage of preferential solubility of product over metal species in supercritical CO2 (or gas-expanded CO2).
