The development and use of allylic organometallic reagents has been an underlying theme of modern organic synthesis.[1] A plethora of methods currently exists for the preparation of diversely substituted allylic organometallic moieties 2 by the displacement of pre-prepared allyl reagents 1 (Scheme 1). The Z group can be a halogen (Cl, Br, I),[1e] chalcogen (O, S, Se, Te),[2] metalloid (Pb, Sn),[3] or hydrogen,[2a, 4] but also carbon (in particular tertiary ...
