摘要:本文以N-(3-溴丙基)邻苯二甲酰亚胺合成为模板反应,研究了相转移催化无溶剂合成N-(-溴烷基)
邻苯二甲酰亚胺的影响因素,实验证实相转移催化剂及其用量、催化剂K2CO3的用量等对反应的影响明显,
得到N-(3-溴丙基)邻苯二甲酰亚胺的优化合成条件为:反应物配比为PA:CgBr2:K2CO3:TBAB=1:2:4:0.2
反应温度80℃,反应时间1h,N-(3-溴丙基)邻苯二甲酰亚胺产率为92%。在相同反应条件下,N-(ω-溴烷基)
邻苯二甲酰亚胺的产率随a,-二溴烷烃的烷基链长度增加而降低。

Abstract: Derivation of alixarenes on the upper/lower ms with igands was the main route to improve their complexation and e-
lective capabilities for separating actinides and lanthanides. N-(A-brmalkyl )phthalimide was an important intermediate in the
synthesis process of calixarene derivatives. In this article, using -(A-bromoalk l)phthalimide as the template, the relation between
the yield of -(a-bromoalk l )phthalimide and reaction conditions were investigated. The yield of N-(A-bromoalkyl)phthalimide
was above 92% through optimizing the reaction conditions. The type of the phase transfer catalysts and their amounts and the a-
mounts ofk C0; were the key influence factors in the N-alk lation of phthalimide reaction by the solvent-free way. In addition, the
increasing of the length of chains would decrease the yield of N-(A-romoalkyl )phthalimide under the same reaction conditions
Key words: phthal mide N-alkylation; phase transfer catalyst solvent-free organic synthesis
