  Cannizzaro-Type Disproportionation of Aromatic Aldehydes to Amides and Alcohols by Using Either a Stoichiometric Amount or a Catalytic Amount of Lanthanide Compounds

  摘要：

  Aromatic aldehydes can be directly converted to the corresponding amides and alcohols in good to excellent yields by the treatment of aromatic aldehydes with lithium amide LiN(SiMe3)(2) in the presence of catalytic lanthanide chlorides LnCl(3) or by the treatment of aromatic aldehydes with a stoichiometric amount of lanthanide amides [(Me3Si)(2)N](3)Ln(mu-Cl)Li(THF)(3) at ambient temperature. The effects of solvents, substitutents on the phenyl ring, and lanthanide metals on the reaction have been examined. The mechanism of the disproportionation reaction was proposed based on the experimental results.

  The reactions of neutral pyrrolyl-functionalized indole with rare-earth metal amides [(Me3Si)2N]3RE(µ-Cl)Li(THF)3 produced the rare-earth metal complexes [(Me3Si)2N]2RE([η1:µ-η2-3-(2-(N-CH3)C4H3NCH=N-CH2CH2)C8H5N])(µ-Cl)Li(THF) (RE = Er, Y) having indolyl ligand η1 bonded to rare-earth metal ion and η2 bonded to lithium ion. The catalytic activities of these lanthanide amido complexes for addition of terminal alkynes to aromatic nitriles were explored. Results reveal that these complexes displayed a good catalytic activity for the addition reaction under mild conditions.

  The development of catalysts capable of catalyzing amidation of esters with amines to construct amides under mild conditions is of great importance. Compared to aliphatic amines, the direct catalytic amidation of esters with less nucleophilic aromatic amines is rather difficult. Employing simple lanthanide tris (amide) complexes Ln[N (SiMe3)2]3(μ‐Cl)Li (THF)3 as the catalysts, it was found a broad

  在温和条件下开发能够催化酯与胺酰胺化以构建酰胺的催化剂非常重要。与脂族胺相比，酯与较少亲核芳族胺的直接催化酰胺化相当困难。采用简单的镧系元素三（酰胺）络合物LN [N（森达3）2 ] 3（μ -Cl）的Li（THF）3作为催化剂，已发现宽范围的芳族胺和酯的被有效地转换成以各种酰胺在温和的条件下丰产。从镧系元素三（酰胺）配合物与底物胺之间的酰胺交换反应开始，实验上证实了这种转化的合理机制。
