Traceless synthesis of benzimidazoles on solid support
Mazurov, Anatoly
, p. 67 - 70 (2000)
Traceless solid-phase syntheses of benzimidazoles and 5-(benzimidazol-2- yl)benzimidazoles on 2-(4-formyl-3-methoxyphenoxy)ethyl polystyrene are described. No auxiliary functional groups are left in the products after ultimate cleavage and cyclization.

The protocol presented here is a new strategy for visible light induced C-H trifluoromethylation at C4 of benzimidazoles using Togni's reagent in the presence of fac-Ir(ppy)3. Its advantages are its operational simplicity, mild reaction conditions, low catalyst loading and wide substrate scope in which electron-withdrawing, electron-donating groups and different protecting groups are tolerated.
Nickel catalyzed alkylation of N-aromatic heterocycles with Grignard reagents through direct C-H bond functionalization

A novel protocol for nickel-catalyzed direct sp2 C-H bond alkylation of N-aromatic heterocycles has been developed. This new reaction proceeded efficiently at room temperature using a Grignard reagent as the coupling partner. This approach prov
