Context: Nucleophilic substitution reactions of aliphatic amines with alkyl halides represent a simple and direct mechanism for obtaining higher-order aliphatic amines. However, it is well known that these reactions suffer from low selectivity due to multiple alkylations, which is at...
The reactions of a variety of alkyl halides and alkylene oxides with t-butylamine and t-octylamine have been investigated. Pure secondary amines were obtained in satisfactory yield. Tertiary amine derivatives were also obtained by the action of methylating agents or of ethylene oxide upon both amine...
The structure of the amines formed by the reaction of metal derivatives of diphenylamine with aralkyl halides 来自 Springer 喜欢 0 阅读量: 18 作者:GA Razuvaev,GA Abakumov,AA Abramova 摘要: A method for the synthesis of diphenylaralkylamines from potassium diphenylamine and aralkyl halides in ...
Alternative synthesis of indole via an intramolecular reaction of 2-aminophenethyl alcohol. N-methylated amines are very important drug molecules and natural products1. Therefore, this transformation is still performed using toxic and/or hazardous methyl halides or sulfates in the agent. Despite this ...

Acylation of amines is the reaction of amines with the acetyl chloride. Complete Step By Step Answer: ... Pyridine is used to remove the side product formed
Traditional methods of obtaining these compounds are the hydroamination of alkenes or alkynes and the amination of aryl halides, the reaction of amines with alkyl halides, reductive amination of aldehydes or carboxylic acids [[7], [8], [9], [10], [11], [12], [13], [14], [15], [...
This copper-catalyzed N-alkylation reaction has excellent scopes for both the alkyl halide and the amine parts; however different types of ligands were still required to achieve high enantioselectivity and reactivity. Generally speaking, alkyl halides predominantly determined the ligand choice; by contrast...
A preferred embodiment of this invention involves preforming the alkali metal omega-aminoalkoxide prior to conducting the reaction with the alkyl halides. The process of this embodiment comprises reacting an alkanolamine (R1)nN(--R--OH)m
