ABSTRACT:
A method of carrying out a reaction comprising the steps of: mixing at least one organic reaction component with at least one fluorous reaction component having the formula:in-line-formulae description="In-line Formulae" end="lead"?X1Sn(R)n[Rs(Rf)]3-n, X1X2Sn[Rs(Rf)]2or O═Sn[Rs(Rf)]2in-line-formulae description="In-line Formulae" end="tail"?wherein n is 1 or 2, R is a C1-C6alkyl group, X1and X2are independently, the same or different, H, F, Cl, Br, I, N3, OR1, OOR1SR1, SeR1, CN, NC, NR1R2, an aryl group, a heteroaryl group, an alkyl group of 1 to 20 carbons, an alkenyl group, an alkynyl group, —C(O)R3, M((Rs′)(Rf′))3, OM((Rs′)(Rf′))3or OOM((Rs′)Rf′))3, wherein M is Si, Ge, or Sn, and wherein R1and R2are each independently the same or different H, an alkyl group, —SO2R3or —C(O)R3, wherein R3is an alkyl group or an aryl group, and wherein Rs and Rs′ are each independently the same or different a spacer group, and wherein Rf and Rf′ are each independently the same or different a fluorous group; carrying out a reaction to produce an organic product; and after producing the organic product, separating any excess of the fluorous reaction component and any fluorous byproduct of the fluorous reaction component using a fluorous separation technique. Several compounds have the formula:in-line-formulae description="In-line Formulae" end="lead"?X1Sn(R)n[Rs(Rf)3-n, X1X2Sn[Rs(Rf)]2or O═Sn[Rs(Rf)]2.in-line-formulae description="In-line Formulae" end="tail"?
