Reaction Conditions:
with thionyl chloride;bromine;sodium hydroxide at 20;Reflux;Hell-Volhardt-Zelinski Bromination;
Steps:
Synthesis of α-brominated fatty acids 5b-f
General procedure: To a flask equipped with a sodium hydroxide trap the corresponding fatty acid 4 (0.065 mol) and thionyl chloride (5 equiv,40 mL, 0.325 mol) were added. The reaction mixture was stirred at 50 °C in a water bath. Then, liquid bromine (3 equiv,5 mL, 0.195 mol) was added dropwise and the reaction mixture was stirred under reflux for 6 h and then at room temperature overnight. The excess of thionyl chloride was then removed by distillation. To a beaker containing distilled water in an ice bath,the dark red residue was slowly added and manually stirred.Afterwards, the solution was heated and subsequently cooled,resulting in the precipitation of a pale yellow solid for the longer chain fatty acids which was decanted, washed with distilled water, and once again submitted to the crystallization procedure.
