Yield	Reaction Conditions	Operation in experiment
	AlCl3; In 2-methylphenyl bromide;	(a) Preparation of 2-bromo-5,6 7,8-tetrahydro-3,5,5,8,8-pentamethylnaphthalene 30 ml of 2-bromotoluene and 14 g (0.11 mol) of AlCl3 were introduced into a three-necked flask, cooling was carried out to 0 C. and a solution of 50 g (0.27 mol) of 2,5-dichloro-2,5-dimethylhexane in 100 ml of 2-bromotoluene was added dropwise, and the reaction mixture was permitted to heat to room temperature. The reaction mixture was poured into water and extracted with dichloromethane. The organic phase was separated by settling, washed with an aqueous sodium bicarbonate solution and evaporated. The product crystallized on stirring in methanol.

Yield	Reaction Conditions	Operation in experiment
		(a) 3,5,5,8,8-Pentamethyl-5,6,7,8-tetrahydro-2-naphthylboronic acid, In a similar manner to Example 3(a), starting with 5 g (17.8 mmol) of <strong>[119999-22-3]3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-bromonaphthalene</strong>, 4.22 g (100%) of boronic acid are obtained.
0.8838 mg		The method of Faul et al. was used. To a 100 mL round bottom flask containing THF (30 mL) was added a 1.6 M solution of ?-BuLi in hexanes (8.0 mL, 12.8 mmol), and the resulting solution was cooled in a dry-ice acetone bath to -78 C with stirring, under nitrogen. To this solution was added a solution of the 2:1 mixture of 32:12 (3.3587 g, 7.88 mmol) in THF (8 mL) over 20 min and the reaction was stirred at -78 C for 10 min, and a mixture of triisopropylborate (4.9 mL, 21.3 mmol) in THF (10 mL) was added dropwise over 20 min. The reaction was stirred at -78 C for 1 h and then warmed to room temperature and stirred for 2 h. The reaction was then quenched with 3 N HC1 (35 mL), and after stirring for 2 h, it was poured into ethyl acetate, the layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, and concentrated in vacuo to give a crude product that was purified by column chromatography (150 mL Si02, ethyl acetate:hexanes 1 :3) to give 33 (0.8838 g, 45%) as a white crystalline solid: 1H NMR (400 MHz, CDC13) ? 8.29 (s, 1H), 7.21 (s, 1H), 2.82 (s, 3H), 1.72 (s, 4H), 1.34 (s, 6H), 1.33 (s, 6H); 13C NMR (100.6 MHz, CDC13) ? 149.4, 142.8, 141.4, 136.3, 128.5, 35.1, 35.0, 34.3, 33.8, 31.8, 31.5, 22.6.
