2-PHENYL-3-BUTYN-2-OL Usage And Synthesis

Chemical Properties

WHITE SEMI-TRANSPARENT CRYSTALS

Uses

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

Uses

2-Phenyl-3-butyn-2-ol is used in an aqueous copper (II)-promoted cycloaddtion to azides leading to triazoles.
