Abstract We have reported previously that an iron (III) complex supported by an anionic pentadentate monoamido ligand, dpaq H (dpaq H= 2-[bis (pyridin-2-ylmethyl)] amino-N- quinolin-8-yl-acetamido), promotes selective C [BOND] H hydroxylation with H 2 O 2 with high regioselectivity. Herein, we report on the preparation of Fe III–dpaq derivatives that have a series of substituent groups at the 5-position of a quinoline moiety in the parent ...
