  p-(2-取代环丙基)-α-甲基苄基氯化物溶剂分解中的取代基效应

  摘要：

  在 80% 丙酮水溶液中测量了对（顺式或反式-2-取代的环丙基）-α-甲基苄基氯的溶剂分解速率，包括相对于氢取代基的给电子和吸电子取代基。反式异构体比相应的顺式衍生物更具反应性，其中环丙基和苯基无法获得最有利的“二等分”构象，环丙基将电子释放到苯环。反式异构体在 45°C 下的相对速率通过 σm 值与 ρ 值为 -3.14 和相关系数为 0.97 的相关性最好，表明环丙烷环是一种较差的共振效应发射器。通过LSFE方程分析取代基效应。

• Direct synthesis of ethers from aldehydes and ketones. One-pot reductive etherification of benzaldehydes, alkyl aryl ketones, and benzophenones

  Benzyl alcohols formed by the reduction of benzaldehydes, alkyl aryl ketones, and benzophenones with sodium tetrahydridoborate in alcohols undergo in situ etherification with the solvent in the presence of a catalytic amount of HCl. Thus the process may be regarded as one-pot transformation of carbonyl compounds into the corresponding benzyl ethers. The yields of ethers depend on the substituent nature

  通过在醇中催化量的四氢硼酸钠将苯甲醛，烷基芳基酮和二苯甲酮还原而形成的苄醇在催化量的HCl的存在下与溶剂进行原位醚化。因此，该方法可以被认为是羰基化合物一锅转化为相应的苄基醚。醚的产率取决于初始羰基化合物的芳族片段中的取代基性质以及用作还原介质的醇。

  Benzylic alcohols and diarylmethanols with electron-donating substituents in the aromatic ring reacted with aliphatic alcohols in the presence of a catalytic amount of HCl to give the corresponding alkyl arylmethyl ethers. The reactivity of diarylmethanols in the intermolecular dehydration depended on the nature of substituents in the aromatic rings and structure of aliphatic alcohol.
