Heterobimetallic lanthanide/sodium phenoxides were found to be efficient catalysts for amidation of aldehydes with amines under mild conditions. The reactivity follows the order Nd < Y < Sm for metals and 2,6-(Me)2C6H3O < 2,6-(iPr)2C6H3O < 2,6-(tBu)2C6H3O for phenoxide groups. In comparison with the corresponding monometallic complexes, heterobimetallic complexes show higher activity and a wider range
