摘要

The direct synthesis of activated strontium and barium with iodobenzene in THF yields the corresponding THF complexes of phenylstrontium and phenylbarium iodide, respectively, which dismutate into the homoleptic compounds MPh₂ and MI₂. Already at low temperatures ether cleavage reactions take place and from this reaction, the oxygen-centered cage [((thf)₂BaPh₂)₄ · (thf)BaO] was isolated and its molecular structure determined.
