Cover Feature: Entry to Sulfonylated Phenanthridines via Strained Cyclic Alcohol/Thianthrenium Salt‐Derived Radicals and SO ₂ ‐Capture under Visible‐Light Photoredox Catalysis (ChemPhotoChem 2/2026)

The Cover Feature depicts a bidirectional route leading to two different destinations, signifying the two distinct types of SVI phenanthridines that can be accessed by a new photoredox strategy. The starting materials, biphenyl vinyl azides, are depicted as tourists taking a joyride atop a steam locomotive on a blue moon day. Energy harvesting from blue moonlight by Ru/Ir-based catalysts and the use of SO2 gas produced from burning coal as fuel in steam locomotives are also depicted as an analogy to our reaction conditions. The tourists choose either the cyclopropanol route, involving HAT, or the thianthrenium salt route, involving SET, to reach the appropriate destination.
