Reaction Steps
Method A of the above general procedure was followed using 2-bromonaphthalene (208 mg, 1.00 mmol), ethyl cyanoacetate (123 mg, 1.09 mmol), pentaphenylferrocenyl ligand (14.0 mg, 0.020 mmol) and Pd(dba)2 (6.0 mg, 0.010 mmol). The reaction mixture was purified by column chromatography on silica gel (1:3 dichloromethane/hexanes) to give the desired product (2194 mg, 91%) as a colorless oil: 1H NMR (CDCl3) δ 7.94 (s, 1H), 7.89-7.82 (m, 3H), 7.55-7.50 (m, 3H), 4.88 (s, 1H), 4.29-4.20 (m, 2H), 1.26 (t, 7.2 Hz, 3H). 13C{1H} NMR (CDCl3) δ 165.00, 133.21, 133.16, 129.35, 128.07, 127.76, 127.51, 127.21, 127.08, 126.96, 124.81, 115.75, 63.38, 43.90, 13.89.
