Catalytic hydrogenation products of aromatic and aliphatic dicarboxylic acids

Hydrogenation of aromatic dicarboxylic acids gave 100 % selectivity to respective cyclohexane dicarboxylic acid with 5 % Pd/C catalyst. 5 % Ru/C catalyst was observed to give over hydrogenation products at 493 K and at lower temperature (453 K) the selectivity for cyclohexane dicarboxylic acids was increased. Hydrogenation of phthalic acid with Ru-Sn/Al2O3 catalyst was observed to give phthalide instead of 1,2-benzene dimethanol or 2-hydroxy methyl benzoic acid. Ru-Sn/Al2O3 catalyst selectively hydrogenated the carboxylic group of cyclohexane dicarboxylic acids to give cyclohexane dimethanol. Use of proper catalysts and reaction conditions resulted in desired products.

Selective heterogeneous palladium-catalyzed hydrogenations of watersoluble alkenes and alkynes

Treatment of water-soluble alkenes or alkynes with palladium(II) acetate and triethoxysilane at room temperature afforded the corresponding hydrogenated products in high yields. Simple introduction of a stoichiometric amount of hydrogen is accomplished by using triethoxysilane as the hydrogen source.

Lactone Formation in Superacidic Media

The reaction of substituted 1-hydroxycyclohexanecarboxylic acids in fluorosulphuric acid has been studied.Cyclisation takes place around 0 deg C, accompanied by rearrangement in appropriate cases, yielding the thermodynamically stable lactone or mixture of lactones.An unexpected feature of these reactions is that the carboxy-substituted cyclohexyl carbocation does not undergo ring contraction, unlike the unsubstituted cyclohexyl carbocation, although the cycloheptyl system contracts to cyclohexyl.We suggest that the cyclohexyl carbocation is strongly stabilised by carboxyl substitution, as a result of through-space interaction between the carboxyl oxygen atom and the carbocation centre.
