WebApr 30, 2004 · A suspension of adipic acid (0.3 g, 2 mmol) in thionyl chloride (4 mL) containing a catalytic amount of triphenylphosphine was heated at reflux until a clear solution was obtained (~ 2 h). The excess thionyl chloride was removed and the residue dissolved in dry CH 2 Cl 2 (10 mL). To this solution octylamine (680 µL, 4.1 mmol) and … WebWhy is pyridine included in the reaction of an acid chloride and an amine or alcohol? Pyridine will neutralize the acid by-product of the reaction. Why is an amide less reactive to nucleophilic acyl substitution than an acid chloride? Nitrogen donates more electron density into the carbonyl.
