cf. following abstract The rates of Br cleavage from 1,2-dibromocyclohexane, 1,2- (I), 2,3- (II), and 9,10-dibromo-trans-decalin (III), 2,3-dibromo-cis-decalin cleavage from 1,2-dibromocyclohexane, 1,2-, 2,3-, and 9,10-dibromo-trans-decalin (I), (II), and (III), 2,3-dibromo-cis-decalin (IV), 1,2-dibromo-1-methylcyclohexane, Me2CBrCHBrMe, 1,2-dibromo-1,2-dimethylcyclohexane, and Me2CBrCBrMe2 by iodine-absolute MeOH were measured at 15-75° and related to the dipole moment. The rate depended on the type of CBr bond (secondary-secondary < secondary-tertiary < tertiary-tertiary; the rate constants of each group differed from those of the previous group by a factor of approx. 102. The conformation as derived from the dipole moment appeared of secondary significance. Quant., the differences in rate constant were too small to verify the 4-center principle for the transition state (Rice and Teller, CA 32, 74056). Suitable, simple, isomeric trans-dibromides with the same C skeleton and fixed axial-axial, axial-equatorial, and equatorial-equatorial positions could not be obtained. The reaction product of 200 g. benzoquinone and 75 l. H2C:CHCH:CH2 was reduced without isolation, with 350 g. Zn dust in 900 ml. glacial HOAc to give 215 g. octalindione, m. 100-2° (1:1 petr. ether-C6H6), of which 60 g. treated with 70 g. KOH and 60 ml. 80% N2H4.H2O in 500 ml. HOCH2CH2OH gave 33.5 g. Octalin, b. 67-73°, n20D 1.4847, n25D 1.4824. Of this 43 g., distilled through a spinning band column, collecting 2 g. fractions, gave: fractions 2-12, pure trans-Δ2-octalin, b10 67.5-8.0° (redistilled over Na, d20 0.89151, n20D 1.4815, n25D 1.4792, MRD 43.52, m. -3.5°), and fractions 18-21, pure cis-Δ2-octalin, b10 73° (redistilled over Na, d20 0.92152, n20D 1.4936, MRD 43.01). The appropriate octalin (10 g.) in 50 ml. anhydrous CHCl3 was treated with 12 g. Br in 50 ml. CHCl3 under anhydrous conditions, and the reaction mixture washed with NaHSO3 and H2O, dried, and evaporated to give a residue which was crystallized from EtOH and recrystallized to give the following decalins: II, m. 84.5-5.5° (EtOH or Me2CO); I, m. 46° (EtOH, petr. ether, or Me2CO); 2,3-dibromo-trans-decalin, m. 61° (30-50° petr. ether); trans-1,2-dibromo-cis-decalin, m. 37° (EtOH). 2,3(a,a)-Dibromo-trans-decalin heated 20 hrs. at 120° gave an equilibrium mixture which was separated by chromatography on Kieselgel eluting with petr. ether (b. 50-6°) to give starting material and 2,3(e,e)-dibromo-trans-decalin, m. 60°, which was reduced with Zn dust in EtOH at 65° to give pure trans-Δ2-octalin.
