題目:Reactions of Sulfur- and Phosphorus-Substituted FluoroalkylatingSilicon Reagents with Imines and Enamines under Acidic Conditions 摘要:Nucleophilic fluoroalkylation reactions of imines and enamines with α-phenylthio, α-phenylsulfonyl,and α-diethylphosphoryl substituted fluorinated silanes have been investigated.The reactions are promoted by hydrofluoric acid generated insitu from potassium hydrodifluoride and trifluoroacetic acid.Sulfur reagents worked well with both imines and enamines,whereas phosphorus reagent efficiently coupled only with enamines |
