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.
