A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling
Angewandte Chemie, EarlyView.An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Unraveling G‐Quadruplex and i‐Motif Coexistence Within a Double‐Stranded DNA
Angewandte Chemie, EarlyView.The relative thermodynamic profiles of G‐quadruplex (G4), i‐Motif (iM), and the duplex counterpart tune the simultaneous G4 and iM formation within a double‐stranded (ds) DNA. ABSTRACT DNA can transiently fold into variable arrangements, which are expected to exploit regulatory functions. Guanine‐rich sequences can fold into G‐quadruplexes (G4s), while
