As a new precursor for a hydrogen-bonded open-shell system, we have designed and synthesized 2,5,8-tri- tert -butyl-4,9-dihydroxyphenalenone 1 from commercially available 2,7-dimethoxynaphthalene in nine steps. The neutral radical generated from 1 with active PbO 2 exhibits higher stability compared with other 6-oxophenalenoxyl derivatives in the solid state. From the results of ESR and ENDOR/TRIPLE
作为氢键开壳系统的新前体,我们从市售的 2,7-二甲氧基萘中分九步设计并合成了 2,5,8-三叔丁基-4,9-二羟基苯甲酮 1。与固态的其他 6-氧代苯氧基衍生物相比,1 与活性 PbO 2 产生的中性自由基表现出更高的稳定性。根据 ESR 和 ENDOR/TRIPLE 光谱和 MO 计算的结果,自由基的结构被确定为具有羟基的单自由基 2。
