Abstract

An efficient procedure for the synthesis of biaryls was catalysed by Fe (acac) 2 and zinc powder in carbon tetrachloride solution at 60° C using arenediazonium salts is reported. Symmetrical bi-aryl molecules with various substituents on the phenyl ring (methyl, trifluoromethyl, halogen, nitro, methoxyl) were synthesised in good yields in a short time under air. Zinc powder was used as reductant in the reaction to facilitate the regeneration ...
