Metal-catalysed approaches to amide bond formation.
Amongst the many ways of constructing the amide bond, there has been a growing interest in the use of metal-catalysed methods for preparing this important functional group. In this tutorial review, highlights of the recent literature have been presented covering the key areas where metal catalysts have been used in amide bond formation. Acids and esters have been used in coupling reactions with...
متن کاملTriphenylphosphine-catalysed amide bond formation between carboxylic acids and amines.
Unactivated carboxylic acids and amines undergo organocatalytic Ph3P/CCl4-mediated amide bond formation by employing in situ reduction of triphenylphosphine oxide to triphenylphosphine in the presence of diethoxymethylsilane and bis(4-nitrophenyl)phosphate.
متن کاملMild Deoxygenation of Aromatic Ketones and Aldehydes over Pd/C Using Polymethylhydrosiloxane as the Reducing Agent**
Herein, a practical and mild method for the deoxygenation of a wide range of benzylic aldehydes and ketones is described, which utilizes heterogeneous Pd/C as the catalyst together with the green hydride source, polymethylhydrosiloxane. The developed catalytic protocol is scalable and robust, as exemplified by the deoxygenation of ethyl vanillin, which was performed on a 30 mmol scale in an ope...
متن کاملRibozyme-catalysed carbon-carbon bond formation.
Numerous RNA molecules with new catalytic properties have been isolated from synthetic combinatorial libraries. A broad range of chemical reactions is catalysed, and nucleic acids can accelerate bond formation between small organic substrates. This review focuses on carbon-carbon bond formation accelerated by in vitro selected ribozymes. Mechanistic investigations and structure-function relatio...
متن کاملGreen Synthesis of Silver Nanoparticles Using Mentha aquatic L Extract as the Reducing Agent
Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...
