A novel synthetic protocol for the preparation of arylethynylzinc bromides has been developed. Thus-obtained organozinc reagents were successfully employed in the subsequent cross-couplingreactions with a broad range of aryl halides providing the corresponding alkynylated compounds in good to excellent yields.
