reductive alkylation reactions of amines using carboxylicacids as nominal electrophiles. The two-step reaction exploits the dual reactivity of phenylsilane and involves a silane-mediated amidation followed by a Zn(OAc)2-catalyzed amide reduction. The reaction is applicable to a wide range of amines and carboxylicacids and has been demonstrated on a large scale (305 mmol of amine). The rate differential between

Dialkylformamides are excellent N-sources in the amination of benzylchlorides when catalysed by a NHC-Pd(II)-Im complex. In the presence of NaOH and the catalyst, variously substituted benzylchlorides and five different dialkylformamides reacted smoothly to afford the corresponding N,N-dialkyl-benzylamines in good to almost quantitative yields in eco-friendly solvent water at 50 °C within 3 h.

thiourea catalyst and Ti(OiPr)4 as a fluoride scavenger allows the amination of benzylic fluorides to proceed in moderate to excellent yields. Preliminary results with S‐ and O‐based nucleophiles are also presented. DFT calculations reveal the importance of hydrogen bonds between the catalyst and the fluorineatom of the substrate to lower the activation energy during the transition state.
我们描述了第一个硫脲催化的CF键活化。使用硫脲催化剂和Ti(O i Pr)4作为氟化物清除剂可使苄基氟化物的胺化反应以中等至极好的收率进行。还介绍了基于S和O的亲核试剂的初步结果。DFT计算揭示了催化剂和底物氟原子之间氢键对于降低过渡态活化能的重要性。
