Boron complexes of meso-hydroxy-substituted dipyrrolyldiketones, as the precursors of negatively charged π-electronic systems, were synthesized via the oxidative introduction of an acetoxy unit at the meso position of dipyrrolyldiketones and subsequent hydrolysis. The anionic site formed upon deprotonation was moderately stabilized by hydrogen-bond-donating pyrrole NH, generating non-complexing anionic species.
内消旋羟基取代的二吡咯二酮的硼配合物，作为带负电荷的π电子体系的前体，是通过在二吡咯二酮的内消旋位置氧化引入乙酰氧基单元并随后水解而合成的。去质子化后形成的阴离子位点通过供氢键的吡咯NH适度稳定，生成非络合阴离子物种。
