Abstract
A Ru(II) catalyzed ortho-hydroxylation of ethyl benzoates with ester as a directing groups enables a facile synthesis of various multifunctionalized arenes from easily accessible substrates. Crucial factors in this transformation are both the TFA/TFAA cosolvent system and the oxidants. The reaction demonstrates excellent reactivity, good functional group tolerance, and high yields.
