MCM-41-supported thioether palladium complex has been prepared via immobilization of 3-(2-cyanoethylsulfanyl)propyltriethoxysilane on MCM-41, followed by reacting with palladium chloride. The complex is an efficient catalyst for Heck carbonylation of aryl halides with aniline or n-butyl alcohol under atmospheric pressure of carbon monoxide. A variety of substituted N-phenylbenzamides and n-butyl benzoates were prepared. Importantly, the complex can be recovered and reused without loss of activity.

Key words: MCM-41, supported palladium catalyst, thioether palladium complex, aryl halide, carbonylation
