In this study, six deep eutectic solvents were synthesized. Research shows that [ChCl][ZnCl2]2 can be used for catalyzing F–C alkylations of electron-rich arenes with aldehydes successfully. After five cycles, the yields remain about 89–94%.
Deep Eutectic Solvent Catalyzed Friedel-Crafts Alkylation of Electron-Rich Arenes with Aldehydes. -Triarylmethanes and diarylalkanes are synthesized by the title method under mild reaction conditions in high yields. The deep eutectic solvent can be directly reused for five cycles without significant loss of activity. -(WANG*, A.; XING, P.; ZHENG, X.; CAO, H.; YANG, G.; ZHENG, X.; RSC Adv. 5 (2015) 73, 59022-59026, http://dx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
