Preparation of All the Possible Ring-deuteriated Benzoic Acids by Reductive Dehalogenation of the Corresponding Halogenobenzoic Acids with Raney Alloys in an Alkaline Deuterium Oxide Solution

Tashiro, Masashi,Nakayama, Kouji,Fukata, Gouki

, p. 2315 - 2318 (2007/10/02)

All the possible undeuteriated benzoic acids were prepared mainly by treatment of the corresponding bromobenzoic acid with Raney Cu-Al alloy in 10percent NaOD-D2O solution. 5>Benzoic acid was obtained from pentafluorobenzoic acid by a similar reaction.However, only 4>benzoic acid was prepared by decarboxylation of 4>phthalic acid.
