An example of homogeneous Mo-catalyzed direct N-alkylation of anilines or nitroarenes with alcohols is presented. The DFT aimed design suggested the easily accessible bis-NHC-Mo(0) complex features a strong hydride-donating ability, achieving effective N-alkylation of anilines or challenging nitroarenes with alcohols. The enhanced hydride-donating strategy should be useful in designing highly active

Nanocatalytic Amination: Herein, a reusable heterogeneous N-doped graphene-based manganesenanocatalyst (Mn@NrGO) for selective N-alkylation of amines with alcohols is described. The heterogeneous nature of the catalyst made it easy to separate for long-term performance, and the recycling study revealed that the catalyst was robust and retained its activity after several recycling experiments.

the cyclotrimerization reaction of acetyls, which was used as a pre-established network to introduce propyl sulfonic acid through post-synthetic modification strategy, for the fabrication of SO3H-COF with graphene-like multilayer structure. SO3H-COF was employed as an effective heterogeneous catalyst for the synthesis of benzimidazoles, the synthesis of benzodiazepines and one-pot reductive amination
