Abstract

The development of methods for the site-selective functionalization of aromatic systems continues to be an area of considerable interest in synthetic organic chemistry. One important tool for the predictable, direct transformation of an aryl compound into its ortho- substituted congener is the heteroatom-directed metalation reaction. 2 Of the many functional groups known to direct metalation to the ortho position, N, N- ...
