PROCESS FOR THE PREPARATION OF SEMIFLUORINATED ALKANES USING GRIGNARD REAGENTS

The present invention provides a method for preparing a compound of formula (I) F-(CF2)n-(CH2)m-Ro (I), wherein n is an integer from 2 to 12, m is an integer from 0 to 7, Ro is a linear or branched saturated alkyl group and o depicts the number of carbon atoms, o is an integer from 1 to 12, and wherein m+o is an integer from 2 to 12; comprising reacting a fluorinated compound of formula (II) F-(CF2)n-(CH2)m-X (II), wherein X is CI, Br, I, MgCl, MgBr, or Mgl, and n and m have the same meaning as in formula (I), with a non-fluorinated compound of formula (III) Ro-Y (III), wherein Y is CI, Br, I, MgCl, MgBr, or Mgl, with the proviso that when X is CI, Br or I, Y is MgCl, MgBr or Mgl, and when X is MgCl, MgBr or Mgl, Y is CI, Br or I, and Ro has the same meaning as in formula (I).

(Me3Si)3SiH-mediated intermolecular radical perfluoroalkylation reactions of olefins in water

Figure presented. Perfluoroalkyl-substituted compounds are regarded as important components of fluorophors and for the introduction of fluorous tags into organic substrates. Their syntheses in organic solvents are achieved through different methods, among which, the addition of perfluoroalkyl radicals to unsaturated bonds represents a convenient choice. On the other hand, intermolecular radical reactions in water have attracted the attention of synthetic chemists as a strategic route to carbon-carbon bond formation reactions. In this paper we undertook the intermolecular addition of perfluoroalkyl radicals on electron rich alkenes and alkenes with electron withdrawing groups in water, mediated by silyl radicals, and obtained perfluoroalkyl-substituted compounds in fairly good yields. The radical triggering events employed consist of the thermal decomposition of an azo compound and the dioxygen initiation. Our results indicate that for intermolecular carbon-carbon bond formation reactions mediated by (Me 3Si)3SiH, the decomposition of the azo compound 1,1′-azobis(cyclohexanecarbonitrile) (ACCN) is the best radical initiator. We also found that water exerts a relevant solvent effect on the rates of perfluoroalkyl radical additions onto double bonds and the H atom abstraction from the silane. Our account provides a versatile and convenient method to achieve perfluoroalkylation reactions of alkenes in water to render perfluoroalkylated alkanes as key intermediates in the synthesis of fluorophors and other fluorinated materials. This is the first report where perfluoroalkyl-substituted alkanes are synthesized through intermolecular radical carbon-carbon bond formation reactions in water, mediated by silyl radicals.
