Abstract

Despite the long-standing existence of transition-metal complexes of 1, 3-dienes1 and the commercial importance of metal-catalyzed additions, oligomerizations, and telomerizations of dienes, 2 the reactivity of diene-metal complexes has been surprisingly little studied. Our interest in this subject has been stimulated by recent reports of the contrasting regioselectivity observed in additions of nucleophiles to (s4-diene) Mo3 and-Pd4 species ( ...
