A general and broad-ranging stereospecific coupling of secondary and tertiary boronic esters with electron-rich aromatics is reported. The reaction involves initial formation of a boronate complex followed by activation of the electron-rich aromatic moiety by an electrophile, which triggers a stereospecific 1,2-migration and subsequent elimination/re-aromatization.
