When solvent effects are included by using CPCM/UAHF model, all computational methods predict the same order of reactivity within each group of amines. In agreement with experimental data, heterocyclic amines have the highest reactivity, with energy barriers calculated between 160 and 225 kJ mol1 ...
Reactivity of [{M(C6F5)2(μ-OH)}2]2- (M = Pd or Pt) toward Aromatic Amines and Malononitrile 来自 ACS 喜欢 0 阅读量: 17 作者:José,Ruiz,Venancio,Rodríguez,Gregorio,López,Jaume,Casabó,Elies,Molins,Carles,Miravitlles 摘要: Binuclear μ-hydroxo-μ-arylamido complexes [Pd2(C6F5)...
light-activated reaction manifold exploiting o-methylbenzaldehydes, which can either undergo a light-induced transformation to an o-quinodimethane (a photocaged diene), susceptible toward a Diels–Alder reaction with maleimides, or a thermal imine formation via a condensation reaction with amines31. ...
The kinetics of the transfer of the nitroso group from N-methyl-N-nitroso-p-toluenesulfonamide to each of seven secondary amines (piperazine, N-methylbenzylamine, piperidine, dimethylamine, morpholine, pyrrolidine, and diisopropylamine) was studied using a wide variety of water/AOT/isooctane microemulsio...
Next, in the presence of a reducing agent, the reaction between these cycloadducts (3) and the primary amines (4) yields secondary amines (6), which can then be reacted in the final step with one of the four reagents, three of which are the acyl chlorides—propionyl chloride (7a), ...
demonstrated that the reaction is extremely fast, and also identified some minor byproducts, namely ammonia and “ninhydrin positive materials”, which are then presumably primary amines (such as other amino acids), although their identities were not determined [123]. Nitrogen oxides are a group ...
ORDER PARAMETERThe enantioselectivity of the di-蟺-methane photorearrangement was studied in chid crystals. Achiral dibenzobarrelene acids 1 and 2 were forced to crystallize as chiral crystals by salt formation with chiral amines. Photolysis of these salts in the solid state yielded photoproducts in...
Environmentally friendly oxidation of primary aliphatic amines to imines has been successfully achieved, under metal-free conditions, by the use of diverse... M Largeron,A Chiaroni,Maurice‐Bernard Fleury - 《Chemistry – A European Journal》 被引量: 155发表: 2008年 Galactose oxidase model: biomi...
Since the cyclohexene could be easily oxidized into allylic carbon-centered radical by DTBP56, and the corresponding allylic amine derivatives extensively exist in natural products and pharmaceuticals57,58, achieving direct synthesis of allylic amines from simple allylic hydrocarbons and amines should be ...
A novel route to unsymmetrical secondary amines hydrogen s~lphide,~ carbon disulphide6 etc. Application of a-dialkylaminonitriles as acyl anion equivalents was first suggested by Stork7 and remains an attractive synthetic In these reactions, both the dialkylamino and the nitrile ... AR Katritzky...
