The stereospecific preparation of two perfluoro-1,3-butadiene synthons; (E)-1-trimethylsilyl-1,2,3,4,4-pentafluoro-1,3-butadiene and (E)-1-tributylstannyl-1,2,3,4,4-pentafluoro-1,3-butadiene

(E)-1-Trimethylsilyl-1,2,3,4,4-pentafluoro-1,3-butadiene (1) can be stereospecifically prepared by Pd(0)/CuI catalyzed cross-coupling of (Z)-1-tributylstannyl-1,2-difluoro-2-trimethylsilylethene with iodotrifluoroethene. The corresponding (E)-1-tributylst

(E)-(1,2-Difluoro-1,2-ethenediyl)bis[tributylstannane], 3, readily undergoes a Pd(PPh3)4/CuI-catalyzed cross-coupling reaction with iodotrifluoroethene to yield (E)-octafluoro-1,3,5-hexatriene, 4, in high isomeric purity. (1Z,3E,5Z)-

Perfluoroalkynylxenonium salts, [RXe][BF4] (R = CF 3C≡C, (CF3)22CFC≡C), reacted with organyl iodides, R'I (R' = 3-FC6H4, C6F 5, CF2 ≡CF, CF3CH2; no reaction with R' = CF3CF2CF2)in anhydrous HF to yield the corresponding asymmetric polyfluorinated iodonium salts, [RR'I][Y]. The action of the arylxenonium salt, [C6F5Xe]-[BF4], and the cycloalkenylxenonium salt, [cyclo-1,4-C6F7Xe]-[AsF6], on 4-FC6H4I gave [C6F5(4-FC 6H4)I][BF4] and [cyclo-1,4-C 6F7(4-FC6H4)I][AsF6], respectively, besides the symmetric iodonium salt, [(4-FC6H4)2 2I][Y]. But the aryl-, as well as the cycloalkenylxenonium salt, did not react with C6F5I, CF2 =CFI, and CF 3CH2I.
CHEMICAL PRODUCTION PROCESSES AND SYSTEMS

Page/Page column 12, (2008/06/13)
Chemical production processes are provided that include reacting a metal comprising olefin to form a conjugated olefin; reacting a heterohalogenated olefin to form a conjugated olefin; reacting a halogenated alkane to form a conjugated olefin; and/or reacting a hydrohalogenated olefin to form a conjugated olefin. Chemical production systems are also provided that can include: a first reactant reservoir configured to house a perhalogenated olefin; a second reactant reservoir configured to house a catalyst mixture; a first reactor coupled to both the first and second reservoirs, the first reactor configured to house a metal-comprising mixture and receive both the perhaloganated olefin form the first reactant reservoir and the reactant mixture from the second reactant reservoir; and a product collection reservoir coupled to the first reactor and configured to house a conjugated olefin.
