PdL4-ArX (Suzuki−Miyaura cross-coupling conditions). In particular, unsaturated acetals yield gem-dialkylbutadienes via the formation of an intermediate π-allyl complex that facilitates an anionotropic alkyl migration; in the case of α-phenyl derivatives, the corresponding cross-coupling products are recovered.
