Reaction of 2-mercapto-1-methylimidazole (methimazole) with tris(dimethylamino)borane, B(NMe2)3, provides the tetrahedral dimethylamine adduct of tris(methimazolyl)borane, [(Me2HN)B(methimazolyl)3]. By contrast, imidazole, 2-methylimidazole, 2-chloroimidazole and benzimidazole provide the homoleptic tetra-azolyl systems H[B(azolyl)4], and the same product is obtained even when a substoichiometric quantity...

The gold(I)-catalyzed synthesis of 2-fluoroalkyl imidazole derivatives was developed. Catalyzed by gold(I), propargyl amidines underwent a 5-exo-dig cyclization to afford 2-fluoroalkyl-5-methyl imidazoles. Also, 2-fluoroalkyl imidazole-5-carbaldehydes were obtained in the presence of NIS. A mechanism investigation manifested the probable process...
