The reduction of aryl diethyl phosphate esters by lithium 4,4'-di-tert-butylbiphenylide (LiDTBB) in THF at 0 °C is described. The reactions can be carried out either stoichiometrically (3.0 equiv LiDTBB) or with only a catalytic amount of DTBB (0.25 equiv) in the presence of lithium (2.1-3.0 equiv) and the phosphate. Products are separated from DTBB by solubility differences, by acid/base vs. neutral
描述了 4,4'-二叔丁基联苯锂 (LiDTBB) 在 THF 中在 0 °C 下还原芳基二乙基磷酸酯。在锂(2.1-3.0 equiv)和磷酸盐存在下,反应可以化学计量(3.0 equiv LiDTBB)或仅使用催化量的 DTBB(0.25 equiv)进行。通过溶解度差异、酸/碱与中性萃取或快速色谱法将产品与 DTBB 分离。
