Bromination of 2-acetyl-5-methylfuran
Saldabol,Popelis,Shatz,Slavinskaya
, p. 161 - 163 (1999)
The bromination of 2-acetyl-5-methylfuran by bromine and N-bromosuccinimide was studied. The action of N-bromosuccinimide on 5-methyl-2-acetylfuran in various solvents leads to mixtures of an ω-bromo ketone, a 5-bromomethyl derivative, and 5-bromomethyl-ω-bromo ketone. The use of 2,2′-azobisisobutyronitrile as activator of the radical process does not make the reaction selective but promotes bromination at the methyl group of the ring. A selective method for the synthesis of 2-(bromoacetyl)-5-methylfuran by the bromination of 2-acetyl-5-methylfuran with bromine was developed. 1999 KluwerAcademic/Plenum.
