Highly functionalized arylmagnesium bromides are readily prepared by an iodine–magnesium exchange reaction. In the presence of catalytic amounts of copper(I) salts and chlorotrimethylsilane, they add to various enones leading to the conjugateaddition products in 66–89% yield.

Various functionalized aryl and heteroaryl aluminum reagents were obtained by performing IâLi or BrâLi exchange reactions with the corresponding unsaturated organic halides in the presence of i-Bu2AlCl. By means of an appropriate catalyst, the resulting new aluminum species were directly acylated, allylated or arylated. 1,4-Michael additions to enones have also been achieved.
