• Selective monoetherification and monoesterificatton of diols and diacids under phase-transfer conditions
  作者：Jaime de la Zerda、Gabriela Barak、Yoel Sasson

  DOI：10.1016/0040-4020(89)80151-6

  日期：1989.1

  Research on the selectivity of etherlfication reactions of diols and esterification reactions of diacids by alkyl halides under phase-transfer catalysis has shown that under such conditions, selectivity of monoetherification increases in the order prim < sec < tert diols, though overall yield of monoether decreases from sec to tert diols. Monoesterification of diacids was accomplished with a high degree

  对相转移催化二醇的醚化反应的选择性和烷基卤化物对二酸的酯化反应的选择性的研究表明，在这种条件下，尽管单醚的总收率从秒至叔二醇。二酸的单酯化以高度选择性完成。发现二醇和二酸的最佳提取通常对应于约5个碳的链长。这可能意味着由于其空间构象，通过内部溶剂化，在催化剂和要反应的阴离子之间形成的络合物对于某些碳长度是稳定的。
