Piperidine is a base
Webbinorganic base [8],[9]. The condensation of aromatic aldehyde and malonic acid in the presence of a base is the well-known Knoevenagel condensation reaction [10]. Usually, ammonia, primary or secondary amines and their salts are employed as base [11]. Use of piperidine as organo-catalyst with pyridine WebbPiperidine Amines are more basic than ethers as oxygen is more electronegative than nitrogen. So oxane is less basic than piperidine. Pyrrole is not a good base as the lone pair of electrons is used to restore aromaticity to the ring. Between pyrrole & pyridine, pyridine is more basic as its lone pair is not involved in resonance.
