  • How are amide bonds formed?

    There are many methods available for the formation of amides, but on paper the most common and simplest approach for amide bond formation is generally a condensation reaction between a carboxylic acid and an amine. Although a very simple concept the initial reaction is an acid base reaction leading to an ammonium salt which is quite stable .

  • What is tertiary amide synthesis?

    A general and efficient method enables the synthesis of tertiary amides from readily available tertiary amines and anhydrides in the presence of FeCl 2 as catalyst and tert -butyl hydroperoxide in water (T-Hydro) as oxidant.

  • Is amide synthesis Universal?

    It is worth noting that the conversion rate of the ester is 100% based on the NMR (Supplementary Fig. 1) results. Therefore, the synthesis of primary amides from esters is universal through this metal amidoborane aided reaction, which can be applied to different types of aromatic and aliphatic esters to obtain high yield amides.

  • Can amides be synthesised directly from esters and amines?

    Efficient synthesis of amides directly from esters and amines is achieved under mild, neutral conditions with the liberation of molecular hydrogen. Both primary and secondary amines can be utilized.
