标题:A New Route To Polyfluorinated Trifluoromethanesulfonates. Synthesis Of Perfluoroallyl And Perfluorobenzyl Triflates
摘要:Polyfluoroalkyl Trifluoromethanesulfonates (Triflates) Can Be Prepared In Good To Excellent Yields By The Reaction Of Halofluoroalkanes Such As Cfc-11,Cfc-113 And Cfc-112 With Boron Triflate At 20-25 Degrees C. Hexafluoropropene (Hfp) Is More Active And Reacts With B(Oso2Cf3)(3) Even At 0 Degrees C To Give Perfluoroallyl Triflate In 68% Yield. octafluorotoluene,1,1,2-Trichloro-3,3,3-Trifluoroprop-1-Ene And Hexafluoro-2,3-Dichloro-But-2-Ene Also Produce The Corresponding Triflates In 30-60% Yields On Reaction With Boron Triflate.

摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.
