The reaction conditions used are much milder than those reported for the chemical decarboxylation and methylation reactions, respectively. The one-pot two-step reaction avoids workup and purification problems caused by the instability of the decarboxylation products. Finally, the cascade yields pmethylated functional styrenes which are more stable and are amendable to various cationic photopolymerizations. Overall, this approach serves as a promising proof of concept, demonstrating robust efficacy with specific substrates; however, further optimization is required to achieve better conversion for the less reactive styrenes.
