Application

2-Phenyl-3-butyn-2-ol was used in the preparation of :
  • (3-methyl-5-isoxazolyl)(phenyl)-methanol
  • 1-(3-methyl-5-isoxazolyl)-1-phenyl-1-ethanol
  • α-methylene cyclic carbonates via reaction with CO2 catalyzed by transition metal salts in ionic liquid
  • copper (II)-promoted cycloaddtion to azides leading to triazoles

Reactions of propargylic alcohols with CO(2) in a [BMIm][PhSO(3)]/CuCl catalytic system to produce the corresponding alpha-methylene cyclic carbonates were conducted with high yields. Mild reaction conditions, enhanced rates, improved yields, and recyclable ionic liquid catalyst systems are the remarkable features
