| Description |
Attachment of metal complex on polymer has direct implication for the development of novel catalyst with recyclability, reusability
and water solubility in the context environmental concern. In this paper, we illustrate a simple strategy to immobilize ruthenium
benzylidene organometallic complex on thermoresponsive polymer. For this, pyridine-substituted poly (N-isopropylacrylamide) has
been synthesized by atom transfer radical polymerization from a suitable initiator. Then, ruthenium benzylidene has been conjugated
by binding with pyridine part of the polymer. Polymer conjugated ruthenium benzylidene is shown to have thermoresponsive
characteristic in water (soluble below lower critical solution temperature (LCST) but precipitates out above LCST in water). Hence it
can act as smart catalyst for metathesis reaction in water. For instance, it can be used as homogeneous metathesis catalyst for allyl
alcohol in aqueous medium below lower critical solution temperature (LCST), that can be recovered as heterogeneous catalyst above
LCST and recycled again as homogeneous catalyst. This is the first example of water-soluble recyclable metathesis catalyst. It is
further demonstrated that steric crowding in the ligand play an important role in the superior performance of the catalyst.
