Aromatic metallacycles are of considerable current interest. Reported aromatic metallacycles are mainly those with carbon, nitrogen, oxygen and sulfur. In this work, we report the synthesis and characterization of aromatic chloroosmacyclopentatrienes, which represent the first structurally confirmed metallaaromatic with a chlorine atom in its framework. Single-crystal X-ray diffraction studies show that these planar chloroosmacyclopentatrienes possess a very short Os-ClC distance suggesting M=ClC bond character.
芳香金属环目前备受关注。已报道的芳香金属环主要是含有碳、氮、氧和硫的那些。在这项工作中，我们报道了芳香氯代锇环戊三烯的合成与表征，它们是首例结构上得到确认且骨架中含有氯原子的金属芳香化合物。单晶X射线衍射研究表明，这些平面的氯代锇环戊三烯具有非常短的Os-ClC距离，表明存在M=ClC键的特征。
