Lead dioxide may also be prepared by the hydrolysis of lead[IV] salts; for example, lead tetrachloride may be hydrolyzed in cold hydrochloric acid solution, or a saturated solution of lead tetraacetate may be hydrolyzed in glacial acetic acid. pbO2还可以通过水解四价铅盐的方法来制备,例如,pbCl4可以在冷的盐酸溶液中水解；而pb(OAc)4的饱和溶液可以在冰醋酸中水解。
Then the protected D-mannitol, mixed with lead tetraacetate, hippuric and acetic anhydride, were refluxed in THF for 18 h in a one-pot two step reaction to afford a chiral precursor (Z)-2-phenyl-4-[(S)-2,3-O-(isopropylidene)]-propylidene-5(4H)-oxazolones. 产物与四乙酸铅、马尿酸、乙酐于THF中回流18 h完成一釜二步反应，纯化后得到含有手性碳原子的环丙烷氨基酸前体(Z)-2 苯基-4-[(S)-2，3-O-(异丙叉)]丙叉?f唑-5-酮，前体中的手性碳原子可作为环丙烷氨基酸衍生物不对称合成的手性源；
