HEXACHLOROBUTADIENE or HEXACHLORO-l,3-BUTADIENE (87-68-3) C4C1 CliC=CClCCl=CCIj Combustible liquid (flash point 195°F/90°C autoignition temp 1125°F/607°C Fire Rating 1). Unless inhibited, may form unstable peroxides in storage. Reacts strongly with oxidizers, aliuninum powder may cause fire and explosion. Mixtures with bromine perchlorate forms heat-, friction-, and shock-sensitive explosive compound. Attacks aluminum, and some plastics and coatings decomposes rubber. Thermal decomposition releases toxic and irritating chloride fumes. On small fires, use dry... 

In a subsequent study, the additivity assumption (dose addition) was tested, using the similarly acting nephrotoxicants tetrachloroethylene, trichloroethylene, hexachloro-1,3-butadiene (HCBD), and l,l,2-trichloro-3,3,3-trifluoropropene (Jonker et al. 1996). The compounds were given to female rats by daily oral gavage for 32 days either alone, at the LONEL and NONEL (= LONEL/4), or in combinations of four (at the NONEL and LONEL/2) or three (at the LONEL/3) (see Table 10.9). 

When hexachloro-1,3-butadiene (81) is reacted with four equivalents of n-butyllithium in diethyl ether, a series of lithiation and elimination reactions gives l,4-dilithio-l,3-butadiyne (82) in good yields (Scheme 30). Ijadi-Maghsoodi and Barton verified this by derivatization with various chlorosilanes in yields up to 94%". ...

In 1978, Weiler and Brennan [63] reported the use of racemic 4-zso-thiazolin-3-one-l-oxide (54) as a dienophile, the structure of which could be considered to be a cyclic sulfinyl acrylamide. It undergoes facile cycloaddition (temperatures under 60 °C are required) with cyclop entadiene, 2,3-dimethyl-1,3-butadiene and 1,3-cyclohexadiene, to afford only one product in each case (Scheme 28). Reactions with anthracene and hexachloro cyclop entadiene required temperatures above 100°C, and were effectively catalyzed by A1C13. Although the stereochemistry of the obtained adducts was not ascertained, the authors suggest that the major one is the result of an endo-approach, which must be favored on the basis of mechanistic considerations. 

The 1H NMR spectra of the polymers were obtained with a Varian HR-300 spectrometer, at 110-120° C, using 5-10% solutions of polymer in hexachloro-butadiene. The effect of temperature and solvent on the H NMR spectrum of a cationically prepared poly(4-methyl-l-pentene) was investigated. Figure 1-3 show the results obtained with carbon disulfide, carbon tetrachloride, o-dichloro-benzene, p-dichlorobenzene, and hexachlorobutadiene.
