Imines – Properties, Formation, Reactions, and Mechanisms

WitrynaClaisen rearrangement is a method of forming carbon carbon bonds. It is an organic chemical reaction named after its discoverer, the German chemist Ludwig Claisen … WitrynaDesigned repeat proteins catalyze the 1,3-dipolar reaction between an imine and a deficient dipolarophile in THF solution to form unnatural nitroproline esters, a reaction … A rearrangement in carbohydrate chemistry involving an imine is the Amadori rearrangement. A methylene transfer reaction of an imine by an unstabilised sulphonium ylide can give an aziridine system. Imine react with dialkylphosphite in the Pudovik reaction and Kabachnik–Fields reaction. Biological … Zobacz więcej 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 … 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' + … Zobacz więcej • Enamine • Schiff base • Carboximidate • Oxazolidine 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 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 … Zobacz więcej harris lake vilas county wi
