and in development of the first two-pore domain potassium channel TWIK-related K+ channel 1-selective agonist possessing in vivo antinociceptive activity , 4-Fluoro ring-substituted ethyl PCA is reported in study of catalysis of Knoevenagel reaction with tertiary amine ionic liquid incorporated Fe3O4 nanoparticles ; in aerobic oxidative cleavage of C=C bond to carbonyl compound , and synthesis of 3-cyano-2pyridones derivatives catalyzed by Au-Co/TiO2 . In this work we have prepared tert-butyl ring-substituted phenylcyanoacrylates (OPCA), RPhCH=C(CN)CO2C(CH3)3, where R is 2-bromo, 3-bromo, 4-bromo, 2-chloro, 3-chloro, 4-chloro, 2-fluoro, 3-fluoro, 4-fluoro, 3-iodo, and explored the feasibility of their copolymerization with styrene. To the best of our knowledge except 4-chloro and 4-fluoro , there have been no reports on either synthesis of these compounds, nor their copolymerization with styrene .
