Abstract
Treatment of the (s-trans-eta(4)-butadiene)tantalocene cation complex 3 (wi th [CH3B(C6F5)(3-)] anion) with phenylacetylene results in the formation of the regioisomeric alkyne-butadiene coupling products 4a (featuring the phe nyl substituent in the beta-position) and 4b (Ph at the alpha-carbon) in a 70:30 ratio. The minor insertion product 4b was characterized by an X-ray c rystal structure analysis. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
