Abstract Directedorthometalation is a useful approach to the regioselective synthesis of polysubstituted aromatics.1 The regioselectivity of the metalation can depend, in some instances, on the relative positions and directing abilities of two or more functional groups, and studies to establish the relative directing abilities of orthometalation groups have been reported.1 The O-aryl carbamates
