WitrynaSynthesis of Imines. Imines are typically prepared by the condensation of primary amines and aldehydes and less commonly ketones. In terms of mechanism, such … 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 … Zobacz więcej Imines are common in nature. The pyridoxal phosphate-dependent enzymes (PLP enzymes) catalyze myriad reactions involving … 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 … Zobacz więcej Hydrolysis The chief reaction of imines, often undesirable, is their hydrolysis back to the amine and the carbonyl precursor. R2C=NR' + H2O ⇌ R2C=O + R'NH2 Precursors to heterocycles Imines are … Zobacz więcej • Enamine • Schiff base • Carboximidate • Oxazolidine • Other functional groups with a C=N double bond: oximes, hydrazones Zobacz więcej
