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
摘要:
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.
