I would like to synthesize propargyl methacrylate for research involving click chemistry. I wanted to buy it, unfortunately it's classified as a "Dangerous Product" in Singapore and the chemical companies can't import it from US. So I looked for literature online that synthesize propargyl methacrylate, and I found one that reacted propargyl alcohol to methacryloyl chloride in the presence of triethylamine and using diethyl ether as a solvent. <http://onlinelibrary.wiley.com.libproxy1.nus.edu.sg/doi/10.1002/pola.22367/pdf
> The problem is Sigma-Aldrich doesn't seem to sell diethyl ether either because of several concerns about it. I would like to know what alternative solvent could I use for diethyl ether? And what should be the properties of the solvent that I should consider in looking for a substitute? I would also appreciate it if anyone could explain the necessity of triethylamine, does it reduce the potential violent reaction that can form due to the production of hydrochloric acid?
