'Lene' and mean: The strong Lewis acid B(C6F5)3 efficiently converts some bis(arylethynyl)benzenes into dibenzopentalenes through a series of Lewis acid induced cyclization reactions at room temperature. Thus the reaction has the potential to be useful in the synthesis of substituted dibenzopentalene derivatives which are difficult to make by conventional means.
“Lene”和刻薄：强路易斯酸 B(C6F5)3 可在室温下通过一系列路易斯酸诱导的环化反应，有效地将一些双（芳基乙炔基）苯转化为二苯并戊二烯。因此，该反应有可能用于合成通过传统方法难以制备的取代二苯并戊二烯衍生物。
