Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Zhurnal Obshchei Khimii called The problem of the structure of Gustavson’s hydrocarbon, Author is Slobodin, Ya. M.; Shokhor, I. N., which mentions a compound: 3229-00-3, SMILESS is BrCC(CBr)(CBr)CBr, Molecular C5H8Br4, Computed Properties of C5H8Br4.
Contrary to Murray and Stevenson (C.A. 38, 1476.9, 3615.1), the Raman spectrum of the hydrocarbon first obtained by Gustavson (J. prakt. Chem. 54, 98, 105(1896)), if it is synthesized by the action of Zn dust on (CH2Br)4C in 80-85% alc., and the product is immediately removed from the reaction mixture (to avoid secondary reactions), then distilled several times (last 2 times over Na), resulting in b. 39-41°, n20D 1.41847, d204 0.7377, MRD 23.25, shows neither the frequency 581 nor 1033 cm.-1, and contains neither spiropentane nor other hydrocarbons with a (CH2)3 ring. By its Raman spectrum, it is a mixture of methylcyclobutane and 2-methyl-1-butene. The presence of small amounts of isoprene is probable. The formation reaction can be represented by C(CH2Br)4 → CH2.CH2.CH2.C:CH2 → CH2CHCME:CH2 +H2 → MeCH2CH2CMe:CH2.
This compound(Pentaerythrityltetrabromide)Computed Properties of C5H8Br4 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
