Radical Hydrobromination Flashcards
1
Q
purpose
A
anti-Markovnikov addition of Br
2
Q
need?
A
HBr, ROOR (peroxide) heat/light —> haloalkane
3
Q
type of mechanism
A
free-radical
4
Q
steps
A
initiation: ROOR –> 2RO radicals
initiation 2: RO radical + HBr —> ROH + Br radical
propagation: Br radical attacks less sub. side, radical forms on more stable carbon
propagation 2: carbon radical attacks H-Br to add H+ and form another Br radical
termination
5
Q
syn or anti?
A
syn
