Reaction of cyclohexanone with dimethylamine
WebThis reaction is essentially an alcohol dehydration (Sec. 10.1), except that it is typically much faster than dehydration of an ordinary alcohol. (Write the mechanism of this reaction as well.) Typically, the dehydration of the carbinolamine is the rate-limiting step of imine formation. This is why imine formation is catalyzed by acids. WebA mixture of cyclohexanone (22.3g, 0.23 mol), dimethylamine hydrochloride (9.9 g, 0.12 mol), and formaldehyde (36.9 g of 37% solution in water) was refluxed (oil bath at 130 oC, 30 min) and then cooled to room temperature. Sodium chloride (4.25g) was added, and the mixture was stirred at 23 0C (20 min).
