nucleophilic addition उदाहरण वाक्य
उदाहरण वाक्य
- Reformatsky enolates are less reactive than lithium enolates or Grignard reagents and hence nucleophilic addition to the ester group does not occur.
- Because the dimethylamide anion is a poor leaving group, the intermediate does not collapse and another nucleophilic addition does not occur.
- The term is also applied to certain nucleophilic addition reactions, such as in the acid catalyzed hydrolysis of nitriles to amides.
- Nucleophilic addition does not occur if kCO * ( the effective force constant for the CO ligand ) is below a threshold value
- The Mannich reaction is an example of nucleophilic addition of an amine to a carbonyl group followed by dehydration to the Schiff base.
- X-ray diffraction confirms sp2 hybridization at boron and its nucleophilic addition reaction with benzaldehyde gives further proof of the proposed structure.
- This mechanism can be referred to as an instance of the ANRORC mechanism : nucleophilic addition ( A N ), ring closing.
- The reaction type is nucleophilic addition of sulfur to a metal carbene formed from the diazoalkane followed by a Stevens-like rearrangement.
- Organometallic compounds, such as organolithium reagents, Grignard reagents, or acetylides, undergo nucleophilic addition reactions, yielding a substituted alcohol group.
- The nucleophilic addition at ethyl acrylate as an ?, ?-unsaturated carbonyl compound is a frequent strategy in the synthesis of pharmaceutical intermediates.
