Homologation of trifluoroacetimidoyl iodides by palladium-catalyzed carbonylation. An approach to α-amino perfluoroalkanoic acids.
摘要:
Homologation of trinuoroacetimidoyl iodides and the related perfluoro-compounds by palladium-catalyst under CO(1atm)-atmosphere in the presence of alcohols gives alpha-imino perfluoroatkanoates which are transformed to alpha-amino perfluoroalkanoic acids.

A novel mechanistic duality has been revealed from the indolyl 1,3-heteroatom transposition (IHT) of N-hydroxyindole derivatives. A series of in-depth mechanistic investigations suggests that two separate mechanisms are operating simultaneously. Moreover, the relative contribution of each mechanisticpathway, the energy barrier for each pathway, and the identity of the primary pathway were shown to
N-Aryl trifluoroacetimidoyl lithiums. synthetic equivalent of trifluoroacetyl carbanion, are prepared from N-aryl trifluoroacetimidoyl iodides by iodine-lithium exchange reaction with n-BuLi in ether at -78-degrees-C and react with various electrophiles, leading to synthetic blocks for trifluoromethylated nitrogen heterocycles.
