摘要:Stoichiometric and catalytic chemical transformations may be carried out in solution using novel fluorous multiphase systems (FMS). The term 'fluorous' is defined as a carbon-fluorine bond rich organic molecule. The FMS consists of a fluorous phase containing a fluorous solvent, typically a fluorocarbon or a fluorohydrocarbon and a reagent or a catalyst containing a sufficient number of fluorous moieties to render it preferentially soluble in the fluorous solvent without impairing the ability of the catalyst or reagent to be effective in the reaction and while maintaining the reaction in a liquid or fluid phase. The nonfluorous solvent may be any suitable organic or nonorganic solvent(s) with limited or no solubility in the fluorous solvent that is effective for dissolving the reactant(s) and most desirably, for separating the resulting product(s). Typically, such solvents have a Hildebrand solubility parameter of at least about 18.0 MPa1/2. Appropriate fluorous moieties are linear, branched and carbocyclic fluorocarbon alkyl chains with high carbon numbers. FMS reagents and catalysts can be prepared by (1) fluorination (i.e., replacement of C--H bonds with fluorine); (2) fluorofunctionalization, e.g., the attachment of fluorous moieties to the reagents or catalysts; or (3) by total synthesis. The invention is useful in separations technology and in catalyst design and synthesis.
