TCI B6451 (CAS 1973375-72-2) is a cationic cyclometalated iridium complex supplied as its hexafluorophosphate salt for use as a visible-light photocatalyst. The fluorinated and trifluoromethylated ligands tune the excited-state redox properties, supporting demanding single-electron transfer and energy transfer processes. It is widely applied in photoredox and metallaphotoredox methodologies, including nickel-catalyzed cross-coupling under mild conditions. Store the catalyst tightly closed in a cool, dry place protected from light, and weigh it in a fume hood using standard personal protective equipment.
