Generation and Use of an Equivalent of Difluoroacetamide or Difluoroacetate Anions Part 3 of the Series: Reactivity of Stable Trifluoroacetaldehyde hemiaminals. Part 2: T. Billard, B. R Langlois, J. Org. Chem. 2002, 67, 997–1000.
摘要:
Ethers of trifluoroacetaldehyde hemiaminals can undergo dehydrofluorination under basic conditions to provide ethers of difluoroketene hemiaminals. The latter behave as equivalents of difluoroacetamide or difluoroacetate anions towards various electrophiles, yielding a range of difluoromethylcarbonyl products.
Reactivity of Stable Trifluoroacetaldehyde Hemiaminals. 2. Generation and Synthetic Potentialities of Fluorinated Iminiums
摘要:
Under Lewis acid activation, hemiaminals of trifluoroacetaldehyde and related (fluoroalkyl)-aldehydes generate iminium species that can react with various nucleophiles to provide fluorinated amines.
