We report the development of a universal and recyclable heterogeneous zinc/imidazole catalyst. The catalyst is recoverable through simple filtration and can be reused at least five times, retaining its catalytic activity. Leached zinc species were not responsible for the observed catalysis based on the hot filtration test and ICP‐MS analysis. The heterogeneous zinc catalyst also promotes chemoselective transesterification over amidation. magnified image
