Imine organic chemistry
In organic chemistry, an imine is a functional group or organic compound containing a carbon–nitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. Imines are common in synthetic and naturally … Zobacz więcej For ketimines and aldimines, respectively, the five core atoms (C2C=NX and C(H)C=NX, X = H or C) are coplanar. Planarity results from the sp -hybridization of the mutually double-bonded carbon and the nitrogen … Zobacz więcej Carbonyl-amine condensation Imines are typically prepared by the condensation of primary amines and aldehydes or ketones. Ketones undergo similar reactions, but less commonly than aldehydes. In terms of mechanism, such reactions … Zobacz więcej Imines are common in nature. The pyridoxal phosphate-dependent enzymes (PLP enzymes) catalyze myriad reactions involving aldimines (or Schiff bases). Zobacz więcej The term "imine" was coined in 1883 by the German chemist Albert Ladenburg. Usually imines refer to compounds with the general formula R2C=NR, as discussed below. In the older literature, imine refers to the aza-analogue of an epoxide. … Zobacz więcej Hydrolysis The chief reaction of imines, often undesirable, is their hydrolysis back to the amine and the … Zobacz więcej • Enamine • Schiff base • Carboximidate • Oxazolidine Zobacz więcej WitrynaThe specially designed coordinated ligand (perimidin-2-imine) in the Cu(II) complex accelerates the reaction rate significantly during the oxidative homocoupling reaction (OHC) and acts as a base for Cu-coordinated alkyne deprotonation. ...
