Abstract

An unprecedented metal insertion into the strong sp2-sp3 aryl-O bond to form 2 is observed for the reaction of [{RhCl(C8H14)}2] (C8H14= cyclooctene) with two equivalents of the aryl ether phosphane 1. This reaction proceeds directly, even at room temperature, with no rhodium insertion into the adjacent weaker ArO-CH3 bond. However, the alkyl-O bond is activated by the reaction of 1 with [Pd-(CF3CO2)2] to give 3. Selectivity of C-O activation can therefore be directed by choice of metal complex.
