Vicinal dichlorine elimination at dichloroalkenes promoted by a well-defined iron(0) complex
Thoreson, Kristen A.,McNeill, Kristopher
, p. 1646 - 1648 (2011)
Dechlorination reactions at sp2 C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

PHOTOREACTIONS OF TETRAFLUORODIPHOSPHINE WITH ALKYNES
Morse, J. G.,Mielcarek, J. J.
, p. 41 - 50 (1988)
The reaction of tetrafluorodiphosphine with several alkynes in the gas phase and under UV irradiation were studied.Simple addition products were obtained in substantial yield from CF3CCH, CF3CCCH3 and CF3CCCF3.Methyl substituted alkynes gave little volatile product while ethyne and diphenyl ethyne gave no volatile addition products.Non-volatile byproducts were obtained, probably polymers, in substantial quantity in the latter instances.Volatile products were characterized by IR and NMR spectra and by mass spectrometry.

Page/Page column 19, (2021/09/11)
A method of producing (Z)-1,1,1,4,4,4-hexafluoro-2-butene (Z-1336mzz) is described. The method utilizes readily available halogenated starting materials, including 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) and carbon tetrachloride.
Method for preparing 1,1,1,4,4,4-hexafluoro-2-butyne through gas phase method
-
Paragraph 0042-0059, (2020/04/17)
The invention discloses a method for preparing 1,1,1,4,4,4-hexafluoro-2-butyne through a gas phase method, wherein hexafluoro-2-chloro-2-butene as a raw material is subjected to a gas phase dehydrochlorination reaction under the catalytic action of a dechlorination catalyst to obtain 1,1,1,4,4,4-hexafluoro-2-butyne. The method has the advantages of simple process, economy, environmental protectionand easy industrialization.
