arylation मीनिंग इन हिंदी

उदाहरण वाक्य

1. An example of an addition reaction involving aryl radicals is the Meerwein arylation.
2. Chan Lam reaction has also been useful for selective transformations e . g . s-arylation
3. In a general scope a Meerwein arylation is any reaction between an aryl radical and an alkene.
4. Direct ?-arylation of saturated aldehydes and ketones can be effected through the combination of photoredox and organocatalytic methods.
5. The development of this direct ?-arylation of aldehydes led to related reactions for the ?-functionalization of cyclic ketones.
6. In particular, ?-arylation of cyclic ketones has been achieved under similar reaction conditions, but using azepane as the secondary amine cocatalyst.
7. Alkylation and arylation of the phosphinimide complexes is possible through alkyllithium or Grignard reagents, giving products such as CpTi ( NPR 3 ) Me 2.
8. Once again, alkylation and arylation are possible, along with substitution of Cl with other ligands such as SCH 2 Ph and N ( SiMe 3 ) 2.
9. Additionally, a one-pot magnesium halogen exchange with subsequent arylation has been developed, showcasing the stability of the Weinreb Nahm amide and providing an operationally simple method for the synthesis of aryl ketones.
10. In a more recent report from the same group, " ? "-arylcarbonyl compounds were found to be good substrates for the copper catalyzed " meta "-selective C-H arylation.
