  A facile route to tetrafluoroallene

  摘要：

  Tetrafluoroallene has been prepared in 72%-75% yield by metallation of either 2-hydropentafluoropropene or 2-bromopentafluoropropene with t-butyllithium followed by thermal elimination of lithium fluoride from the 2-lithiopentafluoropropene. The 2-bromopentafluoropropene route gives the allene free of isobutane.

  A process for producing a fluoroolefin of the formula: CF 3 CY═CX n H p wherein Y is a hydrogen atom or a halogen atom (i.e., fluorine, chlorine, bromine or iodine); X is a hydrogen atom or a halogen atom (i.e., fluorine, chlorine, bromine or iodine); n and p are integers independently equal to 0, 1 or 2, provided that (n+p)=2; comprising contacting, in the presence of a phase transfer catalyst, a compound of the formula: CF 3 C(R 1 a R 2 b ) C(R 3 c R 4 d ), wherein R 1 , R 2 , R 3 , and R 4 are independently a hydrogen atom or a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, provided that at least one of R 1 , R 2 , R 3 , and R 4 is halogen and there is at least one hydrogen and one halogen on adjacent carbon atoms; a and b are independently=0, 1 or 2 and (a+b)=2; and c and d are independently=0, 1, 2 or 3 and (c+d)=3; and at least one alkali metal hydroxide. The alkali metal hydroxide can be, for example, potassium or sodium hydroxide and the phase transfer catalyst can be, for example, at least one: crown ether such as 18-crown-6 and 15-crown-5; or onium salt such as, quaternary phosphonium salt and quaternary ammonium salt. The olefin is useful, for example, as an intermediate for producing other industrial chemicals and as a monomer for producing oligomers and polymers.
