Abstract

BUSTAMANTE, SAÚL E  and  RIVAS, BERNABÉ L. NEW SYNTHESIS METHOD TO OBTAIN A METHACRYLIC MONOMER WITH A PYRYLIUM GROUP. J. Chil. Chem. Soc. [online]. 2017, vol.62, n.2, pp.3558-3561. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072017000200025.

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.
