Novel copolymers of styrene. 10. Bromo and chloro ring-disubstituted propyl 2-cyano-3-phenyl-2-propenoates

Synthesis and Styrene Copolymerization of New Halogen and Methoxy Ring-Trisubstituted Propyl Cyanophenylpropenoates

“…Our purposes in exploration of novel propyl cyanophenylpropenoates were twofold: (1) to utilize aldol condensation for synthesis of alkenes with a variety of potentially reactive functional groups; (2) to employ conventional radical copolymerization of novel functional comonomers with a commercial monomer styrene. Thus, in continuation of our investigation of new of propyl cyanophenylpropenoates (Bates et al, 2019, Humanski et al, 2018, Kharas et al, 2017 we have prepared halogen and methoxy ring-trisubstituted propyl cyanophenylpropenoates (PCPP), RPhCH=C(CN)CO 2 C 3 H 7 , where R is 2-bromo-3-hydroxy-4-methoxy, 5-bromo-2,3-dimethoxy, 5-bromo-2,4-dimethoxy, 6-bromo-3,4-dimethoxy, 2-chloro-3,4-dimetoxy, 5-chloro-2,3-dimetoxy, 4-bromo-2,6-difluoro, 3-chloro-2,6-difluoro, 4-chloro-2,6-difluoro, and explore the feasibility of their copolymerization with styrene. To the best of our knowledge, there have been no reports on either synthesis of these propyl cyanophenylpropenoates, nor their copolymerization with styrene.…”
