Hydrogenative coupling of nitriles with diamines to benzimidazoles using lignin-derived Rh2P catalyst

open access: yesiScience, 2021
Summary: Nitrile (C≡N bond) activation for direct organic synthesis has been less explored so far due to a high redox potential of nitrile and its low dissociation energy of C−CN bond.

Organic chemistry as representation

open access: yesFoundations of Chemistry, 2020
Electron redistribution is the cornerstone of our understanding of chemical reactivity. For the vast majority of organic reactions electrons are assumed to move in pairs providing explanatory mechanisms through the generation of intermediate structures.

Selective synthesis of meta-phenols from bio-benzoic acids via regulating the adsorption state

open access: yesiScience, 2023
Summary: Phenols are important building blocks widely applied in many fields. The pronounced orientational effect of the phenolic hydroxyl group makes achieving selective synthesis of meta-phenols challenging.
