Benzoin esters of aromatic sulfonic acids can be obtained in high yield from benzoin and the respective sulfonyl halide in molar amounts of a base by carrying out the reaction at low temperature in an organic solvent with the addition of water. Aqueous NaOh or KOH can be used as base in this process.
芳香磺酸苄酯可以通过在有机溶剂中在低温下,加水的情况下,以碱的摩尔量下,使用苯亚甲醇和相应的磺酰卤代物进行反应,从而高产率地获得。在这个过程中,可以使用水合氢氧化钠或氢氧化钾作为碱。
