Abstract
A method for separating a homogeneous catalyst from a solution includes forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution and isolating the host-guest compound from the solution. The catalyst may be released from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.
Claims20
A method comprising:
- separating a homogeneous catalyst from a solution by:
- (a) forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution;
- (b) isolating the host-guest compound from the solution;
- and
- (c) releasing the catalyst from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.
A method of performing a catalyzed chemical reaction, the method comprising:
- catalyzing a chemical reaction in a solution using a homogeneous catalyst;
- adding an inclusion compound to the solution, the inclusion compound binding a first isomer of the catalyst to form a host-guest compound including the inclusion compound and first isomer of the catalyst;
- isolating the host-guest compound from the solution;
- and
- releasing the catalyst from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.
A composition comprising a homogeneous catalyst including a transition metal complex having an N-heterocyclic carbene ligand with an azobenzene functional group thereon, the azobenzene functional group being effective to undergo cis-trans isomerization.
