The complexes mimic certain monooxygenases as they rapidly take up O2 followed by demethylation of the anisole moiety (up to 95% yield)." 0 experiments are provided that show competing aryl-oxygen (160%) and alkyl-oxygen (20%) bond cleavage pathways. Introduction of a p-methoxy substituent in the arene moiety of complex 11 decreases the oxygenation rate and led to an unprecedented O2 induced arene-OCH3-OCD, exchange ...
