Abstract

Abstract The tetrahydrofuran-nitrile (CH 3 CN, nC 4 H 9 CN, C 6 H 5 CN)-zeolite (faujasites, mordenite, beta, pentasils) system and its transformations under supercritical conditions were studied. The feasibility of direct synthesis of the corresponding N-acylpyrrolidines from THF and nitriles of aliphatic and aromatic acids was shown for the first time. The dependence of the THF reaction with nitriles on the temperature, the reaction time, the ...
