| 21. | Various secondary alkyl halides are then readily attacked by the modified to give the corresponding stable cobalamin analogs.
|
| 22. | S N 2 reactions are generally favored in primary alkyl halides or secondary alkyl halides with an steric hindrance.
|
| 23. | S N 2 reactions are generally favored in primary alkyl halides or secondary alkyl halides with an steric hindrance.
|
| 24. | During his study of alkyl halides, Ingold found evidence for two possible reaction mechanisms for nucleophilic substitution reactions.
|
| 25. | The configuration of the addition compound, such as with an alkyl halide, is directed by the methyl group.
|
| 26. | Examples of N-alkylation with alkyl halides are the syntheses of benzylaniline, 1-benzylindole, and azetidine.
|
| 27. | "' Bromocyclopentane "'is an alkyl halide with the chemical formula C 5 H 9 Br.
|
| 28. | Nanotubes can also be alkylated with alkyl halides using lithium or sodium metal and liquid ammonia ( Birch reduction conditions ).
|
| 29. | For example, deprotonation and reaction with a simple alkyl halide allows formation of products containing carbon chains attached to the ring.
|
| 30. | Despite broad success with aryl and vinyl couplings, the use of alkyl halides is less general due to several complicating factors.
