INTRODUCTION
5-Methyl-3-vinyl-2-oxazolidinone (V-MOX) is a highly reactive monomer valued for its low viscosity, mild odor, and excellent reactivity. It is widely used as a reactive diluent in UV-curable inks and coatings, where it enhances adhesion, produces brighter colors, and improves safety compared to conventional diluents. In addition, V-MOX serves as a key building block in the synthesis of kinetic hydrate inhibitor (KHI) polymers, which are applied in oil and gas production to prevent hydrate blockages in pipelines.
Manufacture
V-MOX can be synthesized via a two-step process. In the first step, Cu(II)-catalyzed cyclization of (±)-1-amino-2-propanol with carbon monoxide under an oxygen atmosphere affords 5-methyl-2-oxazolidinone. This intermediate then undergoes ruthenium-catalyzed vinylation with acetylene to give V-MOX in good yields. Alternatively, V-MOX can also be obtained through pyrolysis of 3-(1-hydroxyethyl)-5-methyloxazolidin-2-one.
