The synthesis of substituted aryl ketones catalyzed by highly efficient magnetic N-heterocyclic carbene–Pd complex derived from thiamine

An efficient magnetically separable catalytic system based on palladium N-heterocyclic carbene complex of vitamin B1 was synthesized and characterized by ICP, FT-IR, FE-SEM, EDAX, TEM, XRD and VSM. The catalytic amount of this heterogeneous nanocatalyst (0.001 g, 0.210-3 mmol Pd) affords the corresponding aryl ketones in good to excellent yields at proper reaction times.
