Solid sheet of anodic aluminium oxide supported palladium catalyst for Suzuki coupling reactions

Abstract A Pd(II) Schiff base complex supported on anodic aluminium oxide (with Al substrate sheet) was successfully prepared. The prepared nanocatalyst was characterized by SEM, TEM and XPS. The synthesized Pd-based catalyst showed excellent catalytic activity for Suzuki cross-coupling reactions under mild conditions. The catalytic activity did not deteriorate after five repeated cycles. Pd(II) Schiff base complex supported on solid sheets could be separated and recovered easily by taking it out of the reaction solution. The construction of solid sheet supported Pd catalyst would be expected to be a promising system to perform heterogeneous catalytic reactions.
