Abstract

Zirconacyclopentadienes reacted with 2 equiv of allyl chloride in thepresence of either a catalytic or a stoichiometric amount of CuCl andLiCl salts (2 equiv) to give stereodefined 1,4,6,9-decatetraenes in 66-96% yields; Reaction of 1,4,6,9-decatetraenes obtained here such as 4,5,6,7-tetraethyldeca-1,4,6,9-tetraene with 1 equiv of Negishi reagent (Cp(2)ZrCl(2) + 2 n-BuLi) in THF at room temperature for 3 h and subsequent carbonylation at 0 degrees C gave eight-membered-five-memberedfused-ring ketones such as ,6-tetraethylbicyclo[6.3.0]-undeca-3,5-dien-10-one in 76% yield.
