  BiCl3促进去除甲氧基甲基醚/酯衍生物和DFT研究–OC–OC–O–键的裂解

  摘要：

  描述了一种使用三氯化铋（BiCl 3）裂解甲氧基甲基（MOM）-醚和酯衍生物的简单方法。烷基，烯基，炔基，苄基和蒽MOM醚衍生物以及脂肪族和芳香族羧酸的MOM酯均以良好的收率进行了脱保护。为了更好地理解BiCl 3和水在MOM裂解中的分子作用，使用密度泛函理论（DFT）方法研究了两种可能的结合途径。理论结果表明，酚和醇MOM底物对Bi原子的初始结合位点偏好不同，这表明水在促进MOM基团的裂解中起着关键作用。

  摘要：

  锌（II）盐催化缩醛与酰卤之间的反应，以接近定量的产率提供卤代烷基醚。通常，使用0.01 mol％的催化剂，从毫摩尔到摩尔级的反应会在1-4小时内完成。由此获得的卤代烷基醚的溶液可以直接用于酯副产物的存在不干扰的反应中。后处理会破坏过量的卤代烷基醚，从而最大程度地减少此类致癌化合物的暴露。

  Zinc(II) salts catalyze the reaction between acetals and acid halides to provide haloalkyl ethers in near-quantitative yield. Reactions from millimole to mole scale are typically complete in 1−4 h with 0.01 mol % catalyst. The solutions of haloalkyl ethers thus obtained can be utilized directly in reactions in which the presence of the ester byproduct does not interfere. Excess haloalkyl ether is destroyed
