Reactions with ketones and aldehydes
- Primary amines react with carbonyl compounds to form imines. Specifically, aldehydes become aldimines, and ketones become ketimines. In the case of formaldehyde (R’ = H), the imine products are typically cyclic trimers.
RNH2 + R’2C=O → R’2C=NR + H2O
- Secondary amines react with ketones and aldehydes to form enamines. An enamine contains a C=C double bond, where the second C is singly bonded to N as part of an amine ligand.
R2NH + R'(R”CH2)C=O → R”CH=C(NR2)R’ + H2O
