title: 1,1-Cycloaddition of oxalyl dichloride with dialkenylmetal compounds: formation of cyclopentadienone derivatives by the reaction of 1,4,-dilithio-1,3-dienes or zirconacyclopentadienes with oxalyl chloride in the presence of CuCl.
abstract: 1,4-Dilithio-1,3-dienes or zirconacyclopentadienes reacted with oxalyl chloride in the presence of CuCl in a 1,1-cycloaddition manner to give cyclopentadienone derivatives in high yields along with the elimination of CO.
