Reactions
- Ionic electrophilic addition reactions
a)
Electrophilic ionic addition to C=C
via carbocations
Do
not forget re-arrangements …
b)
Electrophilic ionic addition to C=C
via halonium/mercurinium
ions:
c)
Electrophilic ionic addition to C=C
via a four-membered transition state – hydroboration
d)
Electrophilic addition to
conjugated dienes
- Free radical electrophilic addition reactions
- Nucleophilic addition to aldehydes and ketones
Via acid catalysis:
