N-Arylation of protected and unprotected 5-Bromo-2-aminobenzimidazole as organic material: Non-Linear Optical (NLO) properties and structural feature determination through computational approach

The interest in the NLO response of organic compounds is growing rapidly, due to the ease of synthesis, availability, and low loss. Here, in this study, Cu(II)-catalyzed selective N-arylation of 2-aminobenzimidazoles derivatives were achieved in the presence of different bases Et3N/TMEDA, solvent...
