| 21. | When pyrrole is mixed with the desired oxidizing agents at room temperature, the polymerization reaction begins immediately.
|
| 22. | His dissertation was " The raman spectra of pyrrole and some of its deuterium derivatives ".
|
| 23. | Simple monocyclic aromatic rings are usually five-membered rings like pyrrole or six-membered rings like pyridine.
|
| 24. | The mechanism of the Knorr pyrrole synthesis begins with condensation of the amine and ketone to give an imine.
|
| 25. | Use of ammonium hydroxide or ammonium acetate ( as reported by Paal ) gives the N-unsubstituted pyrrole.
|
| 26. | 1-Methylimidazole is also the precursor for the synthesis of the methylimidazole monomer of pyrrole-imidazole polyamides.
|
| 27. | It can be viewed as a structural analog of pyrrole, with antimony replacing the nitrogen atom of pyrrole.
|
| 28. | It can be viewed as a structural analog of pyrrole, with antimony replacing the nitrogen atom of pyrrole.
|
| 29. | Pyrrole rings such as porphyrins have also been used in coating nanomaterials or semiconductors for both homogeneous and heterogeneous catalysis.
|
| 30. | The imine then tautomerizes to an enamine, followed by cyclization, elimination of water, and isomerization to the pyrrole.
