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.
Claims7
A method comprising:
- separating an azobenzene-modified Grubbs homogeneous catalyst from a solution by:
- (a) forming a host-guest compound between a first isomer of the catalyst and a host compound in the solution, the host compound being a cyclodextrin;
- (b) isolating the host-guest compound from the solution;
- and
- (c) releasing the catalyst from the host-guest compound by converting the first isomer of the catalyst to a second isomer of the catalyst.
