A triazine-type condensating agent with high activity, 1-chloro-3,5-bis((octafluoropentyl)oxy)-triazine(DFCT), was synthesized by one-pot two-step method, in which cyanuric chloride(TCT)was used as reactive group and 2,2,3,3,4,4,5,5-octafluoro-1-pentanol(OFP)was used as the source of short fluorocarbon chain. The intermediate(2,4-dichloro-6-((octafluoropentyl)oxy)-triazine, DCFT)and the target product(DFCT)were characterized by FT-IR,1H NMR,13C NMR,19F NMR and mass spectrometry. The reaction conditions were optimized according to the yield of product: Dichloromethane was used as the solvent; sodium hydroxide was used as acid binding agent; n(TCT)∶n(OFP)=1∶2.2; the reaction temperature was 0 ℃ to generate DCFT, and then 30 ℃ to obtain the target product DFCT, and the yield of DFCT was 96%. DFCT was used as a condensating agent to activate carboxylic acid which would react with amines/alcohols to produce amides(Ⅰa-Ⅰc)/esters(Ⅱa-Ⅱc). It showed that DFCT could be used as a condensating agent for amidation and esterification reactions, and the reaction conditions were mild and easy to operate.
