反应详情

To a solution of 1-bromo-2-naphthaldehyde (0.740 g, 0.001 mole) in tetrahydofuran (10 mL) was added triethylamine (0.150 mL, 0.001 mole) followed by diethylphosphite (0.330 mL, 0.002 mole). The reaction mixture was then stirred at room temperature under nitrogen gas for 18 hours. The volatiles then evaporated in vacuo and further dried under vacuum. The resulting solid was triturated with ether and the solid that separated out was collected and dried under vaccum to get 0.935 g of [(1-bromonaphthalene-2-yl)-hydroxymethyl]phosphonic acid diethyl ester
