摘要
Round and round the olefin goes! A cobalt-catalyzed 1,4- hydrobutadienylation of a 1-aryl-substituted 1,3-diene with 2,3-dimethyl-1,3- butadiene yields 1,3,6-triene derivatives in excellent yield and chemoselectivity. The application of a bulky ligand (SchmalzPhos) leads to the selective formation of a single regio- and stereoisomer. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
