N‐bromosuccinimide (NBS)‐mediated one‐pot, green, efficient and practical synthesis of substituted imidazoles and quinoxalines has been achieved by the reaction of styrenes with N‐arylbenzamidines and o‐phenylenediamines, respectively, in a water:1,4‐dioxane mixture. The reaction involves formation of an α‐bromo ketone as an intermediate in the presence of NBS and water, followed by condensation with

N-heterocyclic carbene (aNHC)-based ligand and its use in synthesizing an acetate bridged CH activated palladium dimer (1). In complex 1, the carbene ligand displays an abnormal mode of binding with the palladium(II) ion. We used complex 1 as a catalyst for the oxidative Heck coupling reaction of arylboronic acids with electron-deficient as well as electron-rich olefins at ambient temperature in water to produce
Facile Synthesis of Polysubstituted Imidazoles through CBr<sub>4</sub>-Mediated Tandem Cyclization of Amidines with 1,3-Dicarbonyl Compounds or Ketones
A facile approach to synthesize polysubstituted imidazoles via CBr4 mediated tandem cyclization of amidine with 1,3-dicarbonyl or ketone is described. This metal-free cascade reaction employed CBr4 as promoter and was carried out with a simple operation under mild conditions.

the presence of metal salts. Imidazoles, pyrroles and new pyrrolinones derivatives are isolated in good overall yields. The role of metal salts was investigated as they can act as Lewis acids or electron donors. Mechanisms are proposed suggesting that imidazoles arise from addition of azirine to imines via radical or ionic mechanism; pyrroles and pyrrolinones are obtained from azirines with enamino
