Super long-term highly active and selective hydroformylation in a room temperature-solidifiable guanidinium ionic liquid with a polyether tag

Abstract

Here we report a novel room temperature-solidifiable guanidinium methanesulfonate with a polyether tag and its use in Rh-catalysed biphasic hydroformylation of higher olefins. This novel ionic liquid can efficiently immobilize the Rh-TPPTS catalyst and render super long-term high activity and chemoselectivity, and no significant loss of activity, selectivity or Rh was observed after thirty-five cycles.
