摘要

Abstract A range of aromatic organocopper or organomagnesium compounds undergo smooth cross-coupling reactions with aryl bromides, chlorides, fluorides and tosylates, leading to polyfunctionalized aromatics or heterocycles in the presence of cobalt salts (5-7.5 mol%) as catalysts. Very mild reaction conditions are needed and, in the case of cross- coupling with organocopper compounds, Bu 4 NI (1 equiv) and 4-fluorostyrene (20 mol%) ...
