Abstract
This describes homogeneous catalysts that are recoverable from solution by being phase selective and through host-guest interactions. An example of a method includes separating a water soluble N-heterocyclic carbene homogeneous catalyst from a solution by: (a) forming a host-guest compound between the catalyst and an inclusion compound in the solution; and (b) isolating the host-guest compound from the solution.
Claims20
A method comprising:
- separating a water soluble N-heterocyclic carbene homogeneous catalyst from a solution by:
- (a) forming a host-guest compound between the catalyst and an inclusion compound in the solution;
- and
- (b) isolating the host-guest compound from the solution.
A method comprising:
- catalyzing a chemical reaction in an organic solvent using a water soluble N-heterocyclic carbene homogeneous catalyst to form a reaction mixture;
- forming an aqueous phase in the reaction mixture;
- adding a solvent in which the catalyst is insoluble to the reaction mixture causing the catalyst to migrate to the aqueous phase to form a catalyst-laden aqueous phase;
- and
- extracting the catalyst-laden aqueous phase from the reaction mixture.
A composition comprising a water soluble homogeneous catalyst including a transition metal complex having an N-heterocyclic carbene ligand with a polyethylene glycol group thereon.
