Physical Properties of 3-Ethylsydnone and the Alkyl Substituents

3-Ethyl-4-ethylsydnone was newly synthesized, and the physical properties of 3-ethylsydnone, 3-ethyl-4-methylsydnone and 3-ethyl-4-ethylsydnone at various temperatures were investigated. The highest dielectric constant was for 3-ethylsydnone. The alkyl substituent effect at the 4-position of the syd...

Zusammenfassung:3-Ethyl-4-ethylsydnone was newly synthesized, and the physical properties of 3-ethylsydnone, 3-ethyl-4-methylsydnone and 3-ethyl-4-ethylsydnone at various temperatures were investigated. The highest dielectric constant was for 3-ethylsydnone. The alkyl substituent effect at the 4-position of the sydnone ring on the dielectric constant can be explained by the 13C NMR spectra.
