摘要：

Ortho-amino arenethiolatocopper(I) compounds are excellent catalysts for the cross-coupling reaction of Grignard reagents with acyclic allylic substrates. For example, reaction of n-BuMgI with geranyl acetate in Et(2)O at 0 degrees C yields quantitatively the gamma substitution product, whereas the same reaction in THF at -30 degrees C affords selectively the a substitution product.
