Abstract
We report the synthesis and oxygen-atom transfer (OAT) photochemistry of [Cu(tpa)BrO3]ClO4. In situ spectroscopy and in crystallo experiments indicate OAT proceeds from a Cu–O fragment generated by sequential Cu–O bond cleavage and OAT from BrOx to [Cu(tpa)]+. These results highlight synthetic opportunities in M–O photochemistry and demonstrate the utility of in crystallo experiments to evaluating photochemical reaction mechanisms.
