[DC] 19% tolerated. A halogen atom directly connected to an arene was also tolerated (20, 22-25). Notably, differentiation of two arenes was possible as exemplified in 17-20 and 25. Achieving such chemoselectivity was found challenging under conventional Birch reduction conditions as mixture of products was obtained even if the two arenes are most electronically differentiated (Table , chemical Birch for obtaining 18). Non-conjugated arenes can be reduced to afford 29 and 30 in this method, though the yields were moderate due to the low reactivity. Borderline cases also exist when Ered,arene is close to Ered,FG, and such cases were exemplified in the reduction of 31 and 32. In accord with this simple rubric, when a functional group is more easily reducible, the method is unable to favor the reduction of (hetero)arenes (33-35).
