Boehmite@tryptophan-Pd nanoparticles: A new catalyst for C-C bond formation

A boehmite@tryptophan-Pd nanoparticulate catalyst was prepared by a simple, fast and convenient route. The nanomaterial was characterized using various techniques and employed as a thermally stable catalyst for Heck, Stille and Suzuki cross-coupling reactions. Optimized conditions for these reactions are described. The catalyst could be isolated, post-reaction, by simple filtration and recycled for several consecutive cycles without a notable change in its activity.
