A metallosalen-based microporous organic polymer as a heterogeneous carbon–carbon coupling catalyst†
Abstract
A novel microporous organic polymer framework with built-in metal sites in the skeleton has been synthesized by the Sonogashira–Hagihara reaction using salen-palladium as building units. The new microporous organic polymer possesses a high BET surface area, large pore volume, good stability and acts as a highly efficient robust recyclable heterogeneous catalyst towards carbon–carbon coupling reactions with low catalyst loading.
