6-BROMO-1,1,4,4,7-PENTAMETHYL-1,2,3,4-TETRAHYDRONAPHTHALENE Use and Manufacturing
2, 5-dimethylhexane-2, 5-diol (10.0 g, 68.4 mmol) was stirred in 50 mL of conc. aq. HCl for 16 hr. The reaction was diluted with 50 mL of HReactor under a nitrogen purge to 2, 5-dichloro-2, 5-dimethyl-hexane (18.3 g, 100 mmol), 2-bromotoluene (17.1 g (100mmol) and 1, 2-dichloroethane into a 200 ml by stirring, where the charged aluminum chloride (1.33 g, 10 mmol) all at once and stir at room temperature for 30 minutes. after the reaction was completed, into water, the organic layer was extracted with dichloromethaneThe magnesium treatment, and concentrated under reduced pressure to remove water.Is recrystallized by using methanol Melting point 73 white solid of 6-bromo -1, 1, 4, 4, 7- pentamethyl-1, 2, 3, 4-tetrahydronaphthalene 15 g (yield 53percent) It was obtained.step A-A 100 gal glass-lined reactor was charged with 1a (CAS Reg. No. 110-03-2, 18.1 Kg), toluene (30.4 Kg) and 37percent HCl (225 Kg). The biphasic mixture was stirred overnight at RT. After draining off the lower layer, the toluene solution was added to AlCl
