secondary amine उदाहरण वाक्य

उदाहरण वाक्य

1. "' Diethylamine "'is an organic compound with the formula ( CH 3 CH 2 ) 2 NH . It is a secondary amine.
2. The photocatalyst then oxidizes an enamine species, transiently generated by the condensation of an aldehyde with a secondary amine cocatalyst, such as the optimal isopropyl benzylamine.
3. The most common secondary amines encountered in forensic chemistry include 3, 4-methylenedioxymethamphetamine ( MDMA, the main component in Ecstasy ) and phenethylamines such as methamphetamine.
4. Amino acids containing a secondary amine group ( the only proteinogenic amino acid of this type is proline ) are sometimes named imino acids, though this usage is obsolescent.
5. Similar compounds are monoethanolamine ( MEA ), a primary amine, and diethanolamine ( DEA ), a secondary amine, both of which are also used for amine gas treating.
6. Although this reaction relies on the use of a secondary amine organocatalyst to generate the enamine species which is oxidized in the proposed mechanism, no enantioselective variant of this reaction exists.
7. The secondary amine nitrogen of 2-( 4-Ethoxybenzyl )-5-nitro-1H-benzoimidazole was then alkylated with ( 2-Chloroethyl ) diethylamine to form etonitazene.
8. This process occurs via keto-enol tautomerization to facilitate rotation about a carbon-carbon bond, followed by tautomerization back to the aldehyde, and condensation with the proximal secondary amine.
9. A secondary amine was combined with an aldehyde to form an intermediate azomethine ylide, which underwent a 1, 3-dipolar cycloaddition with an unsaturated oxindole also present in the reaction mixture.
10. The reactions are difficult to control because the reaction product ( a primary amine or a secondary amine ) are often more nucleophilic than the precursor and will thus preferentially react with the alkylating agent.
