WebAt pH < 7, these reactions proceed under general acid catalysis and the reaction rate increases as pH decreases. However, if pH < 3, the reaction rate slows down. Also, at pH ≥ 7, the reaction rate for hydrazone and oxime bond formation slows dramatically. A catalyst is needed to drive the reaction quickly to completion at neutral or higher pH.
WebRecall that most aldehydes and ketones absorb around 1710-30 cm –1, similar to the value displayed by carboxylic acids. Derivatives of carboxylic acids, however, range from around 1670 cm –1 for amides to 1810-30 cm –1 for acid chlorides and anhydrides. WebMar 25, 2024 · The treatment of an aromatic hydrocarbon with an acyl halide or anhydride in the presence of a catalyst composed of a Lewis acid (i.e., a compound capable of accepting an electron pair), most often aluminum chloride (AlCl 3 ), gives an aryl alkyl or diaryl ketone (ArH → ArCOR or ArCOAr′), where Ar represents an aromatic ring.
WebThe reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. The pH for reactions which form imine compounds must be carefully controlled.
