Versuchsvorschrift

1.02 ml (1.02 mmol, 3.00 eq.) of a 1 M solution of BBr3 in CH2Cl2 was added to a solution of 192.9 mg (0.34 mmol) 3-(2′,2″-Diisobutyl-4-methoxy-3-naphthalen-1-ylmethyl-[1,1′:4′,1″]-terphenyl-4″-yl)propionitrile (76) in 20 ml dry CH2Cl2 at 0° C. via syringe. After that the solution was stirred for 3 h at 0° C. and then for 12 h at r.t. The reaction mixture was then added to water and extracted with CH2Cl2. The comb. org. fractions were dried over MgSO4 and evaporated. Column chromatography (hexanes/EtOAc (2+1)) yielded 117.9 mg (0.21 mmol, 62.85%) 3-(4-Hydroxy-2′,2″-diisobutyl-3-naphthalen-1-ylmethyl-[1,1′:4′,1″]terphenyl-4″-yl)propionitrile (32) as a colorless oil.
