| 11. | Direct halogenation of arenes are possible in the presence of light or at high temperature.
|
| 12. | The original procedure involved halogenation of a sulfide, followed by oxidation to the sulfone.
|
| 13. | Free radical halogenation typically produces a mixture of compounds mono-or multihalogenated at various positions.
|
| 14. | Ethane can react with the halogens, especially chlorine and bromine, by free radical halogenation.
|
| 15. | The putative halogenase Orf8 * has been proposed to catalyze the halogenation on both amino acids.
|
| 16. | However, electrophilic substitution is relatively facile at the 5-position, including nitration and halogenation.
|
| 17. | For alkylbenzene derivatives, the alkyl positions tend to be halogenated first in the free radical halogenation.
|
| 18. | Cyclooctane participates in no reactions except those typical of other saturated hydrocarbons, combustion and free radical halogenation.
|
| 19. | This compound may also be " cracked " to mononuclear Re ( I ) carbonyl complexes by halogenation:
|
| 20. | Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
