庞大的（4,6- tbu -苯并恶唑-2-基）甲烷配体体系使含水金属有机钾配合物[(18-冠-6)K{(4,6- tbu - ocnc6 H2)2 CH}⋅H2 O](2)成为史无前例的水稳定反应性有机钾化合物。此外，2是一个罕见的双（苯并恶唑-2-基）甲烷配体与金属离子仅显示o配位的例子。化合物2通过其固态结构被充分表征。并用核磁共振滴定DOSY实验研究了其在溶液中的行为。结果显示，在加入114等量水的情况下，7天后该复合物就完全质子化了。
The bulky bis(4,6-tBu-benzoxazol-2-yl)methane ligand system enabled the synthesis of the water-containing organometallic potassium complex [(18-crown-6)K{(4,6-tBu-OCNC6 H2 )2 CH}⋅H2 O] (2), which is an unprecedented example of a water-stable reactive organopotassium compound. Furthermore, 2 is a rare example of a bis(benzoxazol-2-yl)methanide ligand displaying solely O-coordination to a metal ion. Compound 2 was fully characterized through its solid-state structure. Furthermore, its behavior in solution was investigated by NMR titration DOSY experiments. These revealed full protonation of the complex only after seven days and the addition of 114 equivalents of water.
