摘要：

Syntheses and applications of new bis-piperidinium and bis-pyrrolidinium compounds as effective two-center phase-transfer catalysts are presented. Applications of these catalysts have been explored in etherification and N-alkylation reactions, and comparisons between these catalysts and traditional phase-transfer catalysts such as cetyltrimethylammonium bromide (CTAB) and 1-ethyl-3-methylimidazolium chloride (emim(+)Cl(-)) are presented.
