Highly functionalized arylmagnesium bromides are readily prepared by an iod
ine-magnesium exchange reaction. In the presence of catalytic amounts of co
pper(I) salts and chlorotrimethylsilane, they add to various enones leading
to the conjugate addition products in 66-89% yield. (C) 2000 Elsevier Scie
