Description

General description

1-Formylpiperazine (FPA), a water soluble alicyclic secondary amine, can be prepared by reacting piperazine with methyl formate. It reacts with benzoylisothiocyanate to form 1-formyl-4-(N-benzoylthiocarbamoyl)piperazine. The conformational analysis of FPA based on its vibrational spectral data has been reported. The kinetics of reaction of p-nitrophenyl acetate with FPA in different organic solvents and ionic liquids has been investigated.
