THE APPLICATON OF ULTRASOUND TO THE DI-ALKYLATION AND CYCLO-DI-ALKYLATION OF ETHYL CYANOACETATE UNDER SOLID-LIQUID PHASE TRANSFER CONDITIONS

摘要

Comparative experiments show that ultrasonic irradiation reduces thereaction times and improves the yields in the di-alkylation and cyclo-di-alkylationof ethyl cyanoacetate under solid-liquid phase transfer conditions.
