Abstract
Ortho-amino arenethiolatocopper(I) compounds are excellent catalysts f or the cross-coupling reaction of Grignard reagents with acyclic allyl ic substrates. For example, reaction of n-BuMgI with geranyl acetate i n Et(2)O at 0 degrees C yields quantitatively the gamma substitution p roduct, whereas the same reaction in THF at -30 degrees C affords sele ctively the a substitution product.
