CAS 7515-17-5: 2-Propynoic acid, 3-(4-methoxyphenyl)-, methyl ester

Methyl 3-(4-methoxyphenyl)propiolate is a reactive compound that reacts with protonation, electrophilic addition, and formation of carbocations. It is prepared by the substitution of dimethyl acetal and phenol groups with methyl groups. The x-ray diffraction data for the product was obtained at room temperature by using a preparative x-ray crystallography technique. The product does not react with air or water but will undergo oxidative dimerization to form benzene when exposed to air or water. Methyl 3-(4-methoxyphenyl)propiolate has been shown to react with aromatic compounds as well as substituents such as hydrogen, chlorine, nitro, and acetoxy groups.
