Some sluoroaromatics with electron with drawing group were prepared by a modified Schiemann reaction. In this new method, the diazonium fluoroborate was decomposed directly in the presence of copper powder at room temperature, giving the corresponding fluoroaromatic products in good yields. The simplicity and higher yield make such a modification a practical one.
