biostudies-literatureUnknown81(Pt 2)Sakami T5,10-Bis(phenyl-sulfon-yl)tetra-hydro-dibenzo-penta-lene, C₂₈H₂₂O₄S₂, <b>1</b>, was suc-cessfully synthesized <i>via</i> the photocatalyst-promoted hy-dro-genative transannulation of di-sulfonyl-cyclo-octa-tetra-ene, <b>2</b>, using perylene as the photocatalyst in the presence of (<i>i</i>-Pr)₂NEt under UV-light irradiation (398 nm, 30 W). In this reaction, the cyclo-octa-tetra-ene moiety of <b>2</b> underwent hy-dro-genative transannulation, yielding <b>1</b>. Single-crystal X-ray analysis revealed that both enanti-omers of <b>1</b> are arranged alternately along the <i>a</i> axis of the unit cell. The structure features a wide V-shaped motif consisting of 6-5-5-6 fused rings, with a dihedral angle of approximately 97.2° between the planes of the terminal phenyl-ene rings. Additionally, a pair of phenyl-sulfonyl groups were observed at the <i>exo</i> positions relative to the V-shaped array.Acta crystallographica.
