【Abstract】 Derivation of calixarenes on the upper/lower rims with ligands was the main route to improve their complexation and selective capabilities for separating actinides and lanthanides.N-(ω-bromoalkyl)phthalimide was an important intermediate in the synthesis process of calixarene derivatives.In this article,using N-(ω-bromoalkyl)phthalimide as the template,the relation between the yield of N-(ω-bromoalkyl)phthalimide and reaction conditions were investigated.The yield of N-(ω-bromoalkyl)phthalimide was above 92%through optimizing the reaction conditions.The type of the phase transfer catalysts and their amounts and the amounts of K2CO3 were the key influence factors in the N-alkylation of phthalimide reaction by the solvent-free way.In addition,the increasing of the length of chains would decrease the yield of N-(ω-bromoalkyl)phthalimide under the same reaction conditions.更多还原
