Moreover, we found a dramatic electronic turnover of the α-diazo group, which converts from a weak electrophile to a strong nucleophile under the DBU·[DBU-H]+-DMF-H2O and DBU·[DBU-H]+-DMF-catalyzed conditions via a through-space charge migration. Additionally, water molecules can ...
However, hydroxyl radical as electrophile can oxidize and decompose GO-TCBQ. As shown in Fig. 3a, the HOMO isosurface of GO-TCBQ is very similar with that of GO, indicating electron trans- port from GO to hydroxyl radical in this system. Thus, GO is more prone to electrophilic attack...
Knowledge of the reactivity of nitrenium ions is important since these electrophiles are proposed to be the DNA-binding intermediates responsible for the carcinogenicity of aromatic amines such as 4-aminobiphenyl and 2-aminofluorene. We have recently reported lifetimes of the N-acetyl analogs of the...
Despite these advances, a mild and general platform for the coupling of strong, neutral C(sp(3))-H bonds with aryl electrophiles has not been realized. Here we describe a protocol for the direct C(sp(3)) arylation of a diverse set of aliphatic, C-H bond-containing organic frameworks ...
Special attention has been paid in numerous studies on triel bonds that are formed between elements of the 13th group (triel elements) acting as electrophiles and the electron-rich sites of Lewis base units [23,24]. The triel trivalent centers possess six electrons in the valence shell, thu...
