Reactivity of arenes in substitution and additiopn reactions

Togo, Hideo,Taguchi, Rie,Yamaguchi, Kentaro,Yoikoyama, Masataka

, p. 2135 - 2140 (2007/10/02)

The reactivity of arenes with 4-methylquinoline (substitution) as a typical heteroaromatic base and phenyl vinyl sulfone (addition) as a typical activated olefin has been studied under thermal and irradiation conditions.The results suggest that electron-withdrawing groups on the aromatic ring in arenes are detrimental to reactions.The crystal structures of arenes 10 and 1e are reported.
