Iaroshenko |发布日期:2021.12.21 摘要:Transformations Of Cf3 Group With Nitro Compounds Into Amides Or Schiff Bases Employing Ytterbia As A Catalyst. This Process Proceeds Via C−f Bond Activation, Accompanied With Utilisation Of Si-Based Reductants/oxygen Scavengers - Reductants Of The Nitro Group. The Scope And Limitations Of The Disclosed Methodologies Are Thoroughly Studied. To The Best Of Our Knowledge, This Work Is The First Example Of
