The modulated hydrothermal synthesis (MHT) of an active and selective Hf-MOF-808 material for the N-alkylation reaction of aniline with benzyl alc. under base-free mild reaction conditions is reported. Through kinetic experiments and isotopically labeled NMR spectroscopy studies we have demonstrated that the reaction mechanism occurs via borrowing hydrogen (BH) pathway, in which the alc. dehydrogenation is the limiting step. The high concentration of defective – OH groups generated on the metallic nodes through MHT synthesis enhances the alc. activation, while the unsaturated Hf4+,which acts as Lewis acid site, is able to borrow the hydrogen from the methylene position of benzyl alc. This fact makes this material at least 14 times more active for the N-alkylation reaction than the material obtained via solvothermal synthesis. The methodol. described in this work could be applied to a wide range of aniline and benzyl alc. derivates, showing in all cases high selectivity toward the corresponding N-benzylaniline product. Finally, Hf-MOF-808, which acts as a true heterogeneous catalyst, can be reused at least four consecutive runs without any activity loss.
