Alkylzinc bromides were efficiently prepared by the direct insertion of zinc metal, activated with a catalytic amount of iodine, into alkyl bromides in a polar aprotic solvent. The zinc reagents underwent Ni- and Pd-catalyzed cross-coupling with aryl halides to produce functionalized alkylarenes in excellent yields.
