  羰基化合物的简单、温和和高效的硫代缩醛化和转硫缩醛化以及硫代缩醛的脱保护：硫醇在硫代缩醛化选择性中的独特作用

  摘要：

  二氧化硅负载的硫酸氢钠 (NaHSO 4 .SiO 2 ) 已被用于在室温下在 CH 2 Cl 2 中对羰基化合物进行有效的硫缩醛化和转硫缩醛化。硫缩醛化的选择性取决于用于转化的硫醇。还发现相同的催化剂在室温下在 CH 2 Cl 2 -H 2 O 中对硫缩醛的脱保护有效。

  A simple and efficient catalytic method for dithioacetalization of various carbonyl compounds (saturated and α,β-unsaturated aliphatic, aromatic, heteroaromatic and hindered) with ethanethiol and 1,3-propanedithiol using H-Y and H-mordenite (H-M) zeolites is described. The reaction affords moderate to excellent yields of the corresponding products.

  DOI：10.1080/17415993.2010.542155

  日期：2011.2.1

  Phosphorus pentoxide supported on silica gel (P2O5/SiO2) efficiently acts as a highly active and reusable catalyst for cyclic and non-cyclic S,S-acetalization of a variety of carbonyl compounds under mild, solvent-free and ambient conditions. This method offers significant advantages such as high conversion, clean work-up, short reaction times and simplicity in operation.[GRAPHICS].

• Chemoselective thioacetalization and transthioacetalization of carbonyl compounds catalyzed by immobilized scandium(III) triflate in ionic liquids
  作者：Ahmed Kamal、Gagan Chouhan

  DOI：10.1016/s0040-4039(03)00580-x

  日期：2003.4

  Immobilized scandium triflate [Sc(OTf)(3)] in ionic liquids has been found to be an extremely efficient and recyclable catalyst for the thioacetalization and transthioacetalization of both aromatic and aliphatic aldehydes. Significant rate acceleration and chemoselectivity was achieved by employing this catalytic system. (C) 2003 Elsevier Science Ltd. All rights reserved.
