Abstract A process for synthesizing polysubstituted cyclopentadienone derivative from CO2 includes reducing the temp of 1.4-diiodo-1,3-butadiene dissolved in solvent to -78–30 deg.C, reaction with butyl lithium, introducing CO2, reaction at -78–30 deg.C for 5-10 min and purifying. Its advantages include use of waste to reduce environmental pollution, high output rate and selectivity and easy purification.
