The hexanes obtained by the reaction between Me₃CH and CH₂:CH₂ with BF₃ or AlCl₃ as catalyst are investigated and identified by converting them into Br and NO₂ derivatives and by the Raman spectrum. The hexane fractions consist chiefly of 90-70% Me₂CHCHMe₂ (I), 10-25% Me₂CHPr (II) and of less than 3% Me₃CEt (III). ETCHMeEt and n-hexane cannot be detected and may be present only in traces, if at all. Since I is the only hexane which gives a solid Br derivative on direct bromination, the hexane fraction is brominated in direct sunlight, giving Me₂CBr CBrMe₂ (IV). IV sublimes 165-75° without melting and m. 166-8° (decomposition) in a sealed tube. On further bromination, IV gives Me(BrCH₂)CBrCBr(CH₂Br)Me, m. 130-1°. When boiled with Zn in 95% EtOH, IV gives Me₂C:CMe₂, b₇₆₀ 72°, n²⁰_D 1.4155, which is converted by Thiele’s method (Ber. 27, 456(1894)) into Me₂C(NO)CClMe₂, m. 121°. Me₂CBrCHMe₂ (V), m. 24-5°, and Me₃CCBr₂Me, m. 191.5°, are not formed by direct bromination. The liquid bromides left after the separation of IV consist chiefly of monobromides, b₂₀₀ 75-85°, n²⁰_D 1.45, which are free from V. Nitration of the hexane fraction by boiling 20 cc. with 60 cc. 38% HNO₃ for 6 hrs. gives Me₂C(NO₂)C(NO₂)₂Et, colorless plates or needles, m. 96°, indicating the presence of II in the hexane mixture The presence of III was first observed when a fraction, b₇₆₀ 49.2-9.9°, d²⁰₄ 0.6492, n²⁰_D 1.3689, was obtained. Treatment of this fraction with 38% HNO₃ at 120° and distillation give 3-nitro-2,2-dimethylbutane, b₇₆₀ 168°. It dissolves completely in 5% EtONa in EtOH, remains in solution on addition of an equal volume of H₂O and is precipitated from this solution by CO₂ as an oil. For the results of the Raman spectrum, see C. A. 34, 3205.2. The reactions taking place between Me₃CH and CH₂:CH₂ in the presence of catalysts are briefly discussed.
