Abstract Several methods are available for elongation of fatty acid acyl chains. The present paper describes adaptation to the field a previously published protocol manganese‐based Wurtz type coupling alkyl bromides. 22‐Bromo‐3( Z ),6( ),9( ),12( ),15( ),18( )‐docosahexaene, easily prepared from 4( ),7( ),10( ),13( ),16( ),19( )‐docosahexaenoic acid, was coupled homologous ω‐bromoesters by stir...
