1,1,4,4-Tetramethyl-1,2,3,4-tetrahydronaphthalene Use and Manufacturing
a) l, l, 4, 4-tetramethyl-l, 2, 3, 4-tetrahydronaphth.alene (18): 2, 5-dichloro-2, 5- dimethylhexane (300 mg, 1.64 mmol, 1 eq) was dissolved in dry benzene (25 mL). A1C1In a 250 mL round-bottomed flask was weighed T-1 (11.0 g, 60 mmol). Dry benzene (240 mL) was added and then AICITo a solution of 2, 5-dichloro-2, 5-dimethyl hexane 20(2.0 mmol) in benzene 21 (2 mL mmol-1), AlCl3 (0.2 mmol)was added and the reaction mixture was stirred under refluxin nitrogen atmosphere for 64 h. Excess benzene 21 wasdistilled off and the resulting mixture was poured intodistilled water. The mixture was extracted with ethyl acetateand the organic phase was dried over MgSO4. The solventwas removed under vacuum. The residue was purified bydistillation at low pressure (0.5 mm Hg), and the product 22was collected between 90 and 120 °C as a colorless oil in82percent yield. 1H NMR (300 MHz, CDCl3) δ 1.30 (s, 12H, 3CH3), 1.71 (s, 4H, 2CH2), 7.15 (m, 2H, Ar-H), 7.33 (m, 2H, Ar-H); 13C NMR (75 MHz, CDCl3) δ 31.88, 34.19, 35.10, 125.52, 126.45, 144.74.
