Straightforward etherification of benzyl alcohols (1) via intermolecular dehydration can be efficiently catalyzed by sodium bisulfite under solvent‐free conditions. In the presence of 0.3 mol% or 0.6 mol% amount of sodium bisulfite, symmetric and unsymmetric ethers are prepared from the corresponding alcohols in high yields (up to 95%). Etherification of benzhydryl alcohols is also discussed.
亚硫酸氢钠在无溶剂条件下可通过分子间脱水直接催化苄醇(1)的醚化反应。在存在0.3mol%或0.6mol%量的亚硫酸氢钠的情况下,由相应的醇以高产率(高达95%)制备对称和不对称醚。还讨论了苯甲醇的醚化。
