| 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. |
