Abstract:Anilinobenzoic acid phenyl esters were synthesized from phenyl chloroformate and aniline compounds. The obtained anilinobenzoic acid phenyl esters reacted with hydrazine hydrate to give N-phenyl semicarbazide. Finally, N-phenyl benzaldehyde semicarbazide derivatives were obtained by the reaction of N-phenyl semicarbazides with benzaldehyde. The results showed that this three-step reaction could performed at room temperature with a total yield of 84.7%. It is easy to operate and suitable for industrial production. |
Key words:N-phenyl-N'-benzaldehyde semicarbazone; synthesis; phenyl chloroformate |
