NEW SYNTHESIS METHOD TO OBTAIN A METHACRYLIC MONOMER WITH A PYRYLIUM GROUP
Methacrylic monomers with pyrylium salt derivatives are widely used to detect nucleophilic species. A new synthesis method has been used to obtain a pyrylium salt that is trisubstituted with phenyl groups at positions 2,4, and 6. The phenyl group of the 4-position has a metacrylate group in the para...

| Sumario: | Methacrylic monomers with pyrylium salt derivatives are widely used to detect nucleophilic species. A new synthesis method has been used to obtain a pyrylium salt that is trisubstituted with phenyl groups at positions 2,4, and 6. The phenyl group of the 4-position has a metacrylate group in the para-position. The new synthesis method implies the esterification of 4-hydroxybenzaldehyde, using methacrylic anhydride. The formed compound react with acetophenone to form the pyrylium derivative. The yields of both reactions are greater than those previously reported in the literature. |
