Abstract:
A heterogeneous ZIF-90-based catalyst functionalized with COOH and with a porous structure was facilely prepared for efficient CO2 adsorption and activation to undergo reductive N-formylation with a wide range of amines (15 examples) to furnish N-formamides (78-94% yields). The -COO- species generated by an in situ interaction with amine acts as a key species for activating hydrosilane to capture CO2, and remarkably facilitates a cascade C-N coupling and hydrogenation process. Our findings show a facile strategy for the rational construction of robust active sites for reductive CO2 valorization.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
