実験手順
A solution of 117 g (0.5 mol) of 2-nitro-4-fluorobenzyl bromide and 131 g (0.5 mmol) of triphenylphosphine in 2 L of EtOAc was heated under reflux for 3 h. The mixture was cooled and the solid collected to give 175 g (70%) of [(4-fluoro-2-nitrophenyl)methyl]triphenylphosphonium bromide: 1H NMR (CDCl3) δ 8.2 (m, 1H); 7.8-7.5 (m, 16H); 7.4 (m, 1H); 6.1 (d, 2H). ##STR16##
