The reactivity of a Cu catalyst for oxidative coupling is modulated by a small molecule additive, diethyl malonate, that slows over-oxidation of 2-naphthols. Efficient heterocoupling between electron-rich and electron-poor 2-naphthols/2-naphthylamines affords C(1)-symmetric BINOLs with yields ranging from 35-98%.
