MgⁿBu₂ Catalyzed the Hydroalkoxylation of Carbodiimides

The commercially available alkaline earth-metal compound (MgBu2)-Bu-n can act as a highly efficient pre-catalyst under mild conditions for the catalytic addition of alcohols to carbodiimides. To the best of our knowledge, it has not been reported in alkaline earth-metal catalyzing reactions. A possible mechanistic pathway is proposed based on the stoichiometric experiments and the previously published literature.
