titleOfInvention | A kind of synthetic method of multi-substituted cyclopentadiene |
abstract | The present invention relates to a method for synthesizing multi-substituted cyclopentadiene derivatives. Steps: a) react alkynes represented by formula I with low-valent zirconocene compounds in ether solvents, and then add formula The alkyne shown in II continues to react, and the reaction temperature of the above process is between 25°C and the boiling point of the ether solvent; b) adding diiodomethane, cuprous chloride and ligands shown in formula III to the step a ) in the reaction solution, the reaction temperature is between the freezing point of the ether solvent and -20°C; the temperature is raised to the boiling point of the ether solvent; c) the extraction reaction solution is post-treated to obtain the tetrasubstituted cyclopentadiene shown in formula IV ; The reaction formula is as follows: The invention has high yield, easy-to-obtain raw materials and high separation yield. |
