Polymer incarcerated Palladium catalyzed facile in situ carbonylation for the synthesis of aryl aldehydes and diaryl ketones using CO surrogates at ambient conditions
In this existing work an efficient polymer supported palladium catalyst furfurylamine functionalized Merrifield complex of palladium, [Pd@(Merf-FA)] is synthesized and characterized, which showed excellent catalytic activity towards in situ carbonylation reactions using carbon monoxide surrogates like formic acid and chloroform. Here, we examined catalytic activity of Pd@(Merf-FA) catalyst for the formylation of aryl iodides and cabonylative Suzuki-Miyaura coupling reactions. Pd@(Merf-FA) catalyst was systematically characterized by several techniques like HRTEM, elemental mapping, PXRD, TGA-DTA, FESEM, UV-Vis, EDAX, CHN and AAS analysis. The catalyst is highly recyclable up to six times without showing any significant decrease in catalytic activity. The [Pd@(Merf-FA)] catalyst was proved more efficient compared to the corresponding homomogeneous palladium catalyst. In addition the leaching experiment of the synthesized catalyst is studied which showed that leaching of metal is very low from polymeric support.
