General description

Methyl vinyl ketone (MVK) is an organic compound that belongs to the class of enones. It is a useful synthetic reagent in organic synthesis for the preparation of various organic compounds. MVK is a 3-oxobutyl synthon, which undergoes a 1,4 conjugate addition (Michael addition) reaction. MVK is susceptible to anionic polymerization, therefore it is typically stored with hydroquinone, which inhibits polymerization.

Application

Methyl vinyl ketone can be used as a reagent to synthesize:
  • Isocoumarins by a Pd-catalyzed regioselective cyclization reaction with o-alkynylbenzoates in the presence of LiCl.      
  • Furan and pyrrole derivatives by Rh-catalyzed 1,4-carbonylative addition reaction with arylboronic acids.      
  • Poly(p-hydroxystyrene) compounds via radical copolymerization with p-hydroxystyrene derivatives.     
  • Aryl-thiocyanatobutan-2-one derivatives by reacting with aryldiazonium salts in the presence of copper(II) catalysts.
