Application

Thionyl bromide (SOBr2) can be used as a brominating agent in organic synthesis for the bromination of alcohols, carboxylic acids, alkenes, and ketones.
SoBr2 can be used in the synthesis of:      
  • ortho


  • -Bromoanilides by bromination of ortho C-H bonds of the aryhydroxylamines.      
  • β-Amino bromides from β-aminoalcohols in the presence of DMF as a solvent.      
  • 4,8-Dibromobenzo[1,2-c;4,5-c′]bis[1,2,5]thiadiazole from 1,2,4,5-tetraaminobenzene tetrahydrobromide.
