Nitrogen‐Centered Organic Persistent Radicals Catalyze Redox‐Neutral C─C Bond Forming Reactions
Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.Kuhn verdazyls, discovered over 60 years ago, are shown as effective catalysts for the first time. Their tunable redox properties enable organocatalytic redox‐neutral C─H arylation and C─H trifluoromethylation reactions without light activation.

Medicinal Research Reviews, Volume 45, Issue 5, Page 1423-1451, September 2025.ABSTRACT Photoremovable protecting groups (PPGs) offer a straightforward solution for the temporary inactivation of biologically active substrates and their subsequent controlled release by light irradiation. Their relatively easy design and mode of application have made them useful tools for studying dynamic biological processes in vitro and in vivo ...

Dichloridobis(phenanthridine-κN)zinc(II) [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 In the mol-ecule of the title compound, [ZnCl(2)(C(13)H(9)N)(2)], the Zn(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from two phenanthridine ligands and by two terminal Cl atoms. The dihedral angle between the planes of the phenanthridine ring systems is 69.92 (3)°.
