  Conventional and Microwave Assisted Hydrogenolysis Using Zinc and Ammonium Formate

  摘要：

  The selective deprotection of several N-Bzl amino derivatives to the corresponding amines and the removal of S-Bzl and O-Bzl groups from the protected amino acids with ammonium formate and commercial zinc dust are reported. Many other reducible or hydrogenolysable substituents such as halogens, methoxy, phenol, ester, acid, ethene, and Boc groups are unaffected.

  Polymethylhydrosiloxane (PMHS)/trifluoroacetic acid (TFA): a novel system for reductive amination reactions

  摘要：

  Polymethylhydrosiloxine (PMHS)/trifluoroacetic acid (TFA) was discovered as a novel metal-free system for reductive amination reactions. A variety of(het)aryl amines as well as a representative carbamate and urea were successfully alkylated by benzaldehyde in the presence of PMHS and TFA in dichloromethane at room temperature in moderate to excellent yields (28-87%). Furthermore, this reaction protocol was Successfully applied to the alkylation of p-nitroaniline with a wide range of aldehydes, ketones, and a representative acetal to obtain the alkylated products in yields ranging from 40% to 92%. The current work represents one of the very few examples of PMHS being activated by a Bronsted acid. (C) 2009 Elsevier Ltd. All rights reserved.

  Copper(II) acetate is a versatile, cheap, and simple catalyst for the selective N-monoalkylation of amino derivatives with poor nucleophilic character, such as aromatic and heteroaromatic amines as well as sulfonamides, using in all cases primary alcohols as initial source of the electrophiles, through a hydrogen autotransfer process. In the case of sulfonamides, the monoalkylation process followed

  reactions of amines/amides with alcohols in the past. By employing the aerobic relay race methodology with Pd‐catalyzed aerobic alcohol oxidation being a more effective protocol for alcohol activation, ligand‐free homogeneous palladiums are successfully used as active catalysts in the dehydrative N‐alkylation reactions, giving high yields and selectivities of the alkylated amides and amines. Mechanistic

  可能是因为均相钯催化剂不是典型的借用氢催化剂，因此配体在常规厌氧条件下不能有效活化催化剂，因此过去从未将其用于胺/酰胺与醇的N-烷基化反应中。通过采用好氧接力竞赛方法，并以Pd催化的好氧醇氧化作为更有效的醇活化方案，无配体的均相钯已成功地用作脱水N-烷基化反应中的活性催化剂，从而提供了高收率和高选择性的烷基化酰胺和胺。机理研究表明，该反应很可能是通过我们最近发现并提出的新型中继竞争机制进行的。
• Selective N-monoalkylation of aromatic amines with benzylic alcohols by a hydrogen autotransfer process catalyzed by unmodified magnetite
  作者：Ricardo Martínez、Diego J. Ramón、Miguel Yus

  DOI：10.1039/b901929d

  日期：——

  A new catalyst for an old material: magnetite is a good catalyst for the selective N-alkylation of aromatic amines using benzylic alcohols as electrophiles. The process could be repeated up to eight times without losing effectiveness. The catalyst recycling is very easy, using a simple magnet. The catalyst is selective and could discriminate between aromatic and aliphatic amines, as well as between benzylic and aliphatic alcohols, as the reactions only take place with aromatic amines and benzylic alcohols.

  saturated and unsaturated N-benzyl substituted heterocyclic carbene (NHC) iridum(I) complexes were synthesized. The unsaturated carbene complex [(un-NHC-Bn)Ir(CO)2Cl] in the cis form was prepared via the carbene transfer from the corresponding silver complex to [Ir(COD)2Cl]2 followed by ligand substitution with CO, whereas the saturated complex was obtained via the transfer from (sat-NHC-Bn)W(CO)5.
