Transamidation of primary amides with amines catalyzed by zirconocene dichloride.
Zirconocene dichloride (Cp(2)ZrCl(2)) has been shown to be an effective catalyst for the transamidation of primary amides with amines in cyclohexane at 80 °C in 5-24 hours. For favourable substrates, the reaction can be performed at temperatures as low as 30 °C.
متن کاملNickel-catalyzed transamidation of aliphatic amide derivatives.
Transamidation, or the conversion of one amide to another, is a long-standing challenge in organic synthesis. Although notable progress has been made in the transamidation of primary amides, the transamidation of secondary amides has remained underdeveloped, especially when considering aliphatic substrates. Herein, we report a two-step approach to achieve the transamidation of secondary aliphat...
متن کاملNickel-Catalyzed Reductive Cross-Coupling of (Hetero)Aryl Iodides with Fluorinated Secondary Alkyl Bromides.
A mild and efficient nickel-catalyzed reductive cross-coupling between fluorinated secondary alkyl bromides and (hetero)aryl iodides is described. The use of FeBr2 as an additive successfully overcomes the hydrodebromination and β-fluorine elimination of fluorinated substrates and allows the efficient synthesis of a wide range of trifluoromethyl and difluoroalkyl containing aliphatic compounds ...
متن کاملNickel-catalyzed reductive allylation of aryl bromides with allylic acetates.
This paper highlights Ni-catalyzed allylation of electron-rich aryl bromides with a variety of substituted allylic carbonates using zinc as the terminal reductant, affording E-alkenes regioselectively in good to excellent yields by the addition of aryl to the less hindered allylic carbon. The electron-deficient aryl bromides and chlorides are also highly efficient coupling partners.
متن کاملAmide synthesis via nickel-catalysed reductive aminocarbonylation of aryl halides with nitroarenes.
Aminocarbonylation of aryl halides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the development of nickel catalysis for the first three-component reactions of aryl halides, Co2(CO)8, and nitroarenes under reductive conditions to prod...
