Highly reactive calcium was prepared by lithium biphenylide reduction of calcium iodide in tetrahydrofuran at room temperature. This activated calcium reacts with bromobezene to yield corresponding phehylbromocalcium complexe. These organocalcium reagents can undergo uncleophilic aromatic couping reaction with to form corresponding biphenyl derivatives (4-phenyltolune, 4-phenylanisole).
