WebReaction of 3º-amines with strong acylating reagents may generate acylammonium species reversibly (see below), but these are as reactive as acyl chlorides and will have only a very short existence. This explains why reactions #2 & 3 do not give amide products. ... and the ester exchange reaction (#6) requires a strong acid or base catalyst ... WebEsters can also react with amines or ammonia to form amides. This reaction doesn't involve acid catalysis, so the first step is nucleophilic attack at the carbonyl carbon. Proton transfer follows and loss of the alcohol portion of the ester. This gives us two ways to make amides, this one from esters and the earlier one from acyl chlorides. WebJun 14, 2014 · The suffix "amine" tells you that the compound is an amine. In ethanamide, the suffix "amide" tells you that you have an amide group, that is, a C=O attached to an N atom.
