Methyl Group

The mixtures of isomeric acetates produced by oxidative decarboxylation of the four 3-methyl-norbornane-2-carboxylic acids with lead tetraacetate in benzene have been characterized. The composition of these products depends primarily on the configuration of the methyl group in the starting material. The results are compared with those found for the Pb(OAc)4 decarboxylation of the norbornane-, bornane-, and 2,3,3-trimethylnorbornane-2-carboxylic acids. The formation of the products is interpreted in terms of competitive cationic and SNi substitution.

Catalysed Reaction

Oxidative decarboxylation of 2,3,3-trimethylbutanoic acid with lead tetraacetate in benzene or acetic acid affords mainly 3,3-dimethylbut-2-yl acetate; the major product from the cupric salt catalysed reaction is 3,3-dimethylbut-1-ene. The low yields detected of rearrangement products provide evidence for the intermediacy of organolead and organocopper compounds which decompose by SNi displacement or cyclic cis-elimination. Other reactions discussed are oxidative decarboxylation of adamantane-2-carboxylic acid, deamination of 3,3-dimethylbut-2-ylamine, and thermolysis of bis(2,3,3-trimethylbutanoyl) peroxide and of t-butyl adamantane-2-percarboxylate. A reinterpretation of previous results on the oxidative decarboxylation of exo- and endo-nor- bornane-2-carboxylic acid with lead tetraacetate is presented.
