We report the synthesis and oxygen-atom transfer (OAT) photochemistry of [Cu(tpa)BrO 3 ]ClO 4 . 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 BrO x 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.
