Abstract:
The oxidation of 10-10' singly linked corrole dimers with DDQ at low concentration in CHCl3 afforded meso-meso, β-β, β-β triply linked 2H-corrole dimers (with two inner NH groups in each corrole unit), which exhibited characteristic (1) H NMR and absorption spectra attributable to their nonaromatic electronic networks. These 2H-corrole dimers were reduced with NaBH4 to aromatic 3H-corrole dimers, which were unstable and easily oxidized back to the 2H-corrole dimers upon exposure to air. Bis(zinc(II)) complexes of the 2H-corrole dimers were synthesized and characterized as rare examples of nonaromatic zinc(II) corrole complexes.

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...
