Immobilization and characterization of Pd catalyst on ionic liquid based periodic mesoporous organosilica: As an efficient and reusable catalyst for Sonogashira coupling reaction

In this paper, an ordered mesoporous organosilica with ionic liquid framework supported palladium (Pd@PMO-IL) was synthesized and characterized by using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) techniques. The catalytic application of the Pd@PMO-IL was investigated in Sonogashira coupling reaction that products with good yields were obtained. The recoverability and reusability of the catalyst were also investigated under applied conditions
