Why doesn't radical dibromination occurr, giving the same product of a thermal dibromination? If you look at the Bond Dissociation Energies, you have (kcal/mol): C=C pi bond = 65 C-H allylic sigma bond = 85 C-Br sigma bond = 68 C-Br allylic sigma bond = 50 H-Br sigma bond = 88 The mechanism here implies: 1)C-H abstraction by radical Br (-85 + 88 = +3) 2)C-Br allyl sigma bond formation (+50) Total = 50+3 = 53 kcal/mol With a hypothetical radical dibromination you would have: 1) C=C pi bond breaking (-65) 2) 2 C-Br sigma bond formations (+68*2 = +136) Total = -65+136 = 71 kcal/mol The two pathways should at least compete, but why does only allylic bromination happen while radical dibromination doesn't? I guess some kinetic effect plays a role, maybe affecting the pre-exponential term of the arrhenius equation and slowing down the hypotetical radical dibromination

I‘ve seen NBS used to brominate aromatic compounds with allylic positions on the ring, eg in para substitution to the allylic carbon you had pictured. Is it factors like the reaction solvent that determines its reactivity?
@Felixkeeg3 жыл бұрын
NBS functions as a "Br+"-equivalent. Without bromide ions there is no bromine formation and thus no radical reaction. Core bromination is therefore a result of an nucleophilic attack of the aromatic ring on the bromo-cation. You will need a base to deprotonate the resulting sigma complex.
