低温下，Schlosser碱（nBuLi/tBuOK）对苯的金属化反应在THF中顺利发生，形成了含有苯基阴离子和叔丁醇的离散混合金属Li2K4簇。聚集体本身通过金属化甲苯表现出超碱性行为。以这种方式获得的离域苯阴离子与钾离子结合，从而形成二维配位聚合物。
The metalation of benzene by Schlosser's base (nBuLi/tBuOK) occurs smoothly in THF at low temperatures to afford a discrete mixed-metal Li2K4 cluster that contains phenyl anions and tert-butoxide. The aggregate itself exhibits superbasic behavior by metalating toluene. The delocalized benzyl anion obtained this way bonds to potassium counterions, thereby creating a 2D coordination polymer.
