Observations on the intramolecular Heck reactions of aromatic chlorides using palladium/imidazolium salts
Caddick, Stephen,Kofie, William
, p. 9347 - 9350 (2002)
The intramolecular Heck reaction of aromatic amines and ethers using palladium/imidazolium salts is described. The use of tetra-n-butylammonium halide salts facilitates the reactivity of aromatic chlorides. An unexpected and novel palladium-mediated cyclisation is also described leading to the formation of a tricyclic adduct.

A simple, one-pot and copper-catalyzed coupling reaction for the construction of 1,2-disubstituted benzimidazole derivatives is described. A low-cost copper salt and a weak base K3PO4 were utilized in this reaction. A variety of 1,2-disubstituted benzimidazoles were obtained in moderate to excellent yields.
