Synthesis of triazole-based and imidazole-based zinc catalysts
Imidazole was first reported in 1858 by the German chemist Heinrich Debus, although various imidazole derivatives had been discovered as early as the 1840s. It was shown that glyoxal, formaldehyde, and ammonia condense to form imidazole (glyoxaline, as it was originally named). This synthesis, while producing relatively low yields, is still used for generating C-substituted imidaz… WebIn organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.. The reaction is highly … heath daniel

WebAbstract: Twelve new imidazole-based potential bi- and tridentate ligands were synthesized and characterized. Whereas in the first series the α-amino acid and imidazole moieties were linked by an amino bond, in the second series the tridentate ligands, containing two imidazole groups, were separated by an amide bond. The first series was WebHantzsch Thiazole Synthesis X O SMe S H2N + N i.aqROH S i.L/NH3 R1S R2 O NH4OAc N S Me Me R S H N S TosMIC R H O i. Na2SO3 ii. NH3 N S RO2CMe NH2 i. 2TsNCS ii. I2, py N ...
