Catalysis of New Type Acyclic Polyether Amine in N-Alkylation of Benzotriazole

Abstract

Abstract: Effects of polyethylene glycols, quaternary ammonium salt and acyclic polyether amine on the yields of N-alkylation of benzotriazolc in liquid-liquid phases were examined.Selecting better a-cyclic polyether aminc as phase transfer catalyst, alkylhalids as alkylating agents, we have synthesized seven N-alkyl benzotriazoles.The results show that acyclic polyether amine is good liquid-liquid phase transfer catalyst and the yields of the N-alkylated products are high.

Key words: Acyclic polyether amine(Ⅲ), Benzotriazcie, N-alkylation, Phase transfer catalysis
