Yield	Reaction Conditions	Operation in experiment
95%	With hydrogen bromide; acetic anhydride; at 0℃; for 24h;Reflux;	Aq HBr (48%, 7 mL, 42 mmol) was added dropwise to Ac2O (12mL, 126 mmol) at 0 C. To this solution, HO(CH2)14OH (0.44 g, 1.9mmol) was added and the mixture was brought to reflux for 24 h. After the mixture had cooled to r.t., the dihalide was extracted with hexanes and was then washed with excess H2O to remove the remaining AcOH, leaving an off-white solid; yield: 0.65 g (95%). The spectroscopic properties were identical to those previously published.
85%	With carbon tetrabromide; triphenylphosphine; In tetrahydrofuran; for 16h;Schlenk technique; Inert atmosphere;	A Schlenk flask was charged with 7 (5.00 g, 21.70 mmol),CBr4 (21.59 g, 65.10 mmol), and THF (250 mL). Then PPh3 (17.80 g, 65.10 mmol) was addedin portions with stirring. After 16 h, water (200 mL) was added and the aqueous phase extractedwith CH2Cl2 (3 × 200 mL). The combined organic layers were dried (MgSO4) and filtered. Thesolvents were removed by rotary evaporation. Hexanes (500 mL) were added to the brown residue,and the precipitate (O=PPh3) removed by filtration. The solvent was removed from the filtrateby rotary evaporation and the residue chromatographed (SiO2 column, 4 cm × 30 cm, hexanes).The solvent was removed from the product containing fractions to give 8 (6.57 g, 18.45mmol, 85%) as a white powder, mp 51 C; lit: 47.5-48.0 C [S5].

Yield	Reaction Conditions	Operation in experiment
85%		1,14-Dibromotetradecane (0.50 g, 1.40 mmol) was dissolved in 4-methyl-2- pentanone (2.0 ml) and 4-pentylpyridine (0.52 g, 3.50 mmol) was added. The mixture was stirred at reflux for 18 h under a nitrogen atmosphere, and the solvent was removed under reduced pressure. The residue was then diluted with H2O (~ 15 ml) and washed with dry Et2O (3 x 20 ml). The aqueous layer was extracted with CH2Cl2 (3 x 20 ml), then the CH2Cl2 layer was concentrated under reduced pressure. The residue was purified by Al2O3 chromatography (neutral, activity II-III), using gradient elution (starting with CHCl3/MeOH = 2% to 10 %). The combined fractions were then passed down a column of Lewatit MP-64 anion resin (Cl"), eluting with EtOH. The resulting fractions were combined and the solvent removed under reduced pressure to give the above compound as a light brown waxy oil (0.67 g, 85 %). 1H NMR (300 MHz, J4-MeOD): δ 8.94 (4H, d, J = 6.5 Hz, CH(2',6')), 8.02 (4H, d, J = 6.5 Hz, CH(3',5')), 4.65 (4H, t, J = 7.5 Hz, CH2(I)), 3.02 (4H, t, J= 7.5 Hz, CH2(I")), 2.07 (4H, m, CH2(2)), 1.82 (4H, m, CH2(2")), 1.42 (28H, m, CH2(3,4,5,6,7,3",4")), 0.98 (6H, m, CH3(5")). 13C NMR (300 MHz, J4- MeOD): 164.2, 144.1, 128.5, 61.2, 35.6, 31.6, 31.5, 29.8, 29.7, 29.6, 29.2, 26.2, 22.5, <n="40"/>13.6, 1 signal obscured or overlapping.
