This invention provides novel substituted benzimidazoles of formula II which are useful as tachykinin receptor antagonists. This invention also provides methods for treating a condition associated with an excess of tachykinin which comprises administering to a mammal in need thereof one of a series of substituted benzimidazoles. This invention further provides pharmaceutical formulations comprising one or more of the substituted benzimidazoles of the present invention in association with pharmaceutical carriers, diluents, or excipients.

AerobicoxidativeCHfunctionalization of primary aliphatic amines has been accomplished with a biomimetic cooperative catalytic system to furnish 1,2‐disubstituted benzimidazoles that play an important role as drug discovery targets. This one‐pot atom‐economical multistep process, which proceeds under mild conditions, with ambient air and equimolar amounts of each coupling partner, constitutes a

The synthesis, structure, optical and redox properties as well as photovoltaic studies of iridium(III) complexes with cyclometalated 2-arylbenzimidazoles decorated with various polyaromatic fragments and an ancillary aromatic β-diketone are reported. Despite the strong preference of the iridium(III) ion to form bis- or tris-cyclometalated complexes in which the metal participates in five-membered metallacycles
