1 Aluminium triflate as a Lewis acid catalyst for the ring opening of epoxides in alcohols D. Bradley G. Williams* and Michelle Lawton a Department of Chemistry, University of Johannesburg, P.O. Box 524, Auckland Park, 2006 Fax: +27(0) ; Tel: +27(0) ; dbgw@rau.ac.za Supplementary Information All compounds were determined to be >99% pure on the basis of GC-FID analyses (total peak area), taken together with clean NMR spectra, after isolation by column chromatography and/or vacuum distillation. Copies of three 13 C NMR spectra are included as examples. Regioisomers were distinguished on the basis of ghmbc and ghmqc NMR experiments. 2-Methoxy-2-phenylethanol, IR ν max (CHCl 3 ) 3398, 2870, 1452, 1355, 1063 cm H NMR (300 MHz; CDCl 3, TMSCl): δ 2.97 (s, 1H, OH), 3.29 (s, 3H, OCH 3 ), 3.59 (dd, J = 11.7, 8.4, 1H, CH 2B OH), 3.69 (dd, J = 11.7, 3.9, 1H, CH 2A OH), 4.3 (dd, J = 8.4, 3.9, 1H, CHOCH 3 ), (m, 5H, H-aromatic), 13 C NMR (300 MHz; CDCl 3 ): δ 56.7 (CH 3 ), 67.2 (CH 2 ), 84.8 (CH), (ortho), (para), (meta), (ipso); m/z (EI) 153 (M +, 5%), 135 (10), 121 (100). 2-Ethoxy-2-phenylethanol, IR ν max (CHCl 3 ) 3589,3011, 2978, 1101, 1032 cm H NMR (300 MHz; CDCl 3 ): δ 1.21 (t, J = 6.9, 3H, CH 3 ), 2.93 (br s, 1H, OH), (m, 2H, OCH 2 CH 3 ), 3.58 (dd, J = 11.7, 3.9, 1H, CH 2B OH), 3.66 (dd, J = 11.7, 8.4, 1H, CH 2A OH), 4.40 (dd, J = 8.4, 3.9, CHOCH 2 CH 3 ), (m, 5H, H-aromatic). 13 C NMR (300 MHz; CDCl 3 ): δ 15.1 (CH 3 ), 64.3 (CH 2 CH 3 ), 67.1 (CH 2 OH), 82.8 (CHOCH 2 CH 3 ), (ortho), (para), (meta), (ipso); m/z (EI) 149 (M +, 10%), 135 (100), 107 (60), 79 (60). 2-Phenyl-2-propoxyethanol, IR ν max (CHCl 3 ) 3588, 2965, 2878, 1101, 1031 cm H NMR (300 MHz; CDCl 3 ): δ 0.92 (t, J = 7.5, 3H, CH 3 ), 1.62 (sx, J = 7.5, 2H, CH 2 CH 3 ), 2.87 (s, 1H, OH), (m, 2H, OCH 2 CH 2 CH 3 ), 3.59 (dd, J = 11.7, 4.2, 1H, CH 2B OH), 3.68 (dd, J = 11.7, 8.3, 1H, CH 2A OH), 4.40 (dd, J = 8.3, 4.2, 1H, CHOCH 2 ), (m, 5H, H-aromatic), 13 C NMR (300 MHz; CDCl 3 ): δ 10.4 (CH 3 ), 22.9 (CH 2 CH 2 CH 3 ), 67.2 (OCH 2 CH 2 CH 3 ), 70.7 (OCH 2 OH), 82.8 (CHOH), (ortho), (para), (meta) (ipso); m/z (EI) 181 (M +, 5%), 165 (20), 150 (100), 122 (60), 108 (98), 91 (25), 79 (50). 2-iso-Propoxy-2-phenylethanol, IR ν max (CHCl 3 ) 3586, 3009, 2975, 1117, 1030 cm H NMR (300 MHz; CDCl 3 ): δ 1.16 (d, J = 6.0, 3H, CH 3 ), 1.23 (d, J = 6.0, 3H, CH 3 ), 3.13 (s, 1H, OH), (m, 3H, OCH(CH 3 ) 2, CH 2 OH), 4.56 (dd, J = 8.1, 3.9, CHOCH(CH 3 ) 2, (m, 5H, aromatics), 13 C NMR (300 MHz; CDCl 3 ): δ 21.0 (CH 3 ), 23.1 (CH 3 ), 67.1 (CH 2 OH), 69.1 (OCH(CH 3 ) 2 ), 79.9 (CHOCH(CH 3 ) 2 ), (ortho), (para), (meta), (ipso); m/z (EI) 181 (M +, 2%), 150 (40), 122 (20), 108 (100), 79 (50). 2-Butoxy-2-phenylethanol, IR ν max (CHCl 3 ) 3588, 2958, 2935, 1100, 1031 cm H NMR (300 MHz; CDCl 3 ): δ 0.95 (t, J = 7.5, 3H, CH 3 ), (m, 2H, CH 2 CH 3 ), (m, 2H, CH 2 CH 2 CH 3 ), 2.51 (s, 1H, OH), 3.37 (dt, J = 9.3, 6.3, OCH 2B ), 3.49 (dt, J = 9.3, 6.3, OCH 2A ), (m, 2H, CH 2 OH), 4.45 (dd, J = 8.4, 4.3, CHOCH 2 ), (m, 5H aromatics), 13 C NMR (300 MHz; CDCl 3 ): δ 13.9 (CH 3 ), 19.3 (CH 2 CH 3 ), 31.9 (CH 2 CH 2 CH 3 ), 67.4 (CH 2 OH), 68.9
