Supported palladium ions inside periodic mesoporous organosilica with ionic liquid framework (Pd@IL-PMO) as an efficient green catalyst for S-arylation coupling

In this paper, highly porous periodic mesoporous organosilica (PMO) with ionic liquid pore walls based on dialkyl imidazolium bridge was synthesized and then, Pd ions were supported onto PMO (Pd@IL-PMO). Subsequently, the synthesized Pd@IL-PMO was successfully incorporated as a heterogeneous catalyst in two types of S-arylation reactions. These catalytic reactions in the presence of Pd@IL-PMO had high product yields. The catalyst was characterized by FT-IR, TEM, SEM, EDX, XRD, TGA and atomic absorption spectroscopy (AAS). Recyclability of the catalyst was confirmed by reusing it for 10 successful runs. (C) 2016 Elsevier Inc. All rights reserved.
