Ortho-metallation of anthracene derivative with alkyllithium is hampered by the preferential attack of the anion to the C(9) and/or C(10) positions. Use of n-BuLi-t-BuOK effected a clean and regioselective metallation at C(2) and subsequent reaction with Me3SiCl or Me3SnCl afforded the corresponding arylsilane or arylstannane in high yields.
