Exchange Reactions of Deuterated Benzene Derivatives in Alkaline Medium. II. Deactivating Substituents^1-3

Abstract

Reduction of an 87.7-mg. (0.23-mmole) sample of the tosyl ester 15b with zinc and acetic acid as previously described afforded a quantitative yield (49.4 mg.) of the crude ketone 9b, m.p. 100-104°. This ketone 9b, which melted at 108.9-109.3°a fter recrystallization from ether, was identified with the previously described sample by a mixed melting point deter-
