YieldReaction ConditionsOperation in experiment
52% A 50-mL well-dried Schlenk flask was charged with argon through a Schlenk line. To a solution of alkenes (20.0 mmol) and KOt -Bu (2.5 g, 22.3 mmol) in THF (20 mL), nBuLi in hexane (2.5 M, 8.8 mL, 22.0 mmol) was added dropwise at -78 C over 1 h. The mixture was stirred at -40 C for 1 h and cooled again to -78 C. A solution of DBTCE (6.51 g, 20.0 mmol) was added over 15 min and the mixture was stirred at -60 C for 1 h. The reaction mixture was allowed to come to RT and stirred for 2 h. The reaction mixture was quenched with saturated ammonium chloride (20 mL), the aqueous layer was extracted with diethyl ether (3 × 20 mL), and the combined organic layers were washed with brine (25 mL), dried over Na2SO4 , and concentrated under vacuum. The residue was purified by column chromatography (silica gel, 50 g, petroleum ether) to give the product. 2-Bromonorbornene (2): 1 H NMR (400 MHz, CDCl3) delta = 6.01 (d, J = 3.0 Hz, 1H), 2.87-2.91 (m, 2H),1.65-1.69 (m, 2H), 1.60 (m, 1H), 1.10-1.20 (m, 3H). 13 C NMR (100 MHz, CDCl3) delta = 134.8, 125.6, 50.4, 48.1,44.0, 25.9, 24.3.

YieldReaction ConditionsOperation in experiment
A 50-mL well-dried Schlenk flask was charged with argon through a Schlenk line. A solution of n-BuLi in hexane (2.5 M, 4.4 mL, 11.0 mmol) was added to a solution of dry diisopropylamine (1.55 mL, 11.1 mmol) in dry THF (10 mL) at 0 C and cooled at -78 C. A solution of monobromides (10.0 mmol) in dry THF (10 mL) was added over 15 min and the mixture was stirred at the same temperature for 1 h. A solution of DBTCE (3.3 g, 10.1 mmol) in dry THF (10 mL) was added dropwise and the temperature was left to rise to RT overnight. The reaction mixture was quenched with saturated ammonium chloride (20 mL), the aqueous layer was extracted with diethyl ether (3 × 20 mL), and the combined organic layers were washed with brine (25 mL), dried over Na2SO4 , and concentrated under vacuum. The residue was purified by column chromatography (silica gel, 50 g, petroleum ether). 2,3-Dibromonorbornene (3): 1 H NMR (400 MHz, CDCl3) delta = 2.98-3.03 (m, 2H), 1.78 (dt, J = 8.2 and1.6 Hz, A part of AB system, 1H), 1.69 (AA? part of AA?BB? system, 2H), 1.32 (BB? part of AA?BB? system,2H), 1.21 (dt, J = 8.2 and 1.8 Hz, A part of AB system, 1H). 13 C NMR (100 MHz, CDCl3) delta = 125.4, 51.6,47.0, 25.7.
