Copper(l) tert-butoxide-promoted coupling of arylsilanes possessing a 1-hydroxyalkyl group at the o-position with organic halides proceeded to give disubstituted arenes. The results indicate that an intermediary arylcopper species is formed by aromatic Csp(2)-to-O silyl migration. (C) 2003 Elsevier Ltd. All rights reserved.
