反应详情

A mixture of 3-nitrobenzyl bromide (17.3 g, 0.08 mol), triethyl phosphite (13.3 g, 0.08 mol) in toluene (200 mL) was stirred at reflux for 24 h. The reaction mixture was cooled and evaporated in vacuo. Chromatography of the residues on SiO2 eluting from 0–100% ethyl acetate in petroleum ether (60–80° C.) gave the title compound (14.8 g, 68%) as a yellow liquid.
