Electrochemical direct carboxylation of benzyl alcohols having an electron-withdrawing group on the phenyl ring was successfully carried out by constant current electrolysis using an undivided cell equipped with a platinum plate cathode and a magnesium rod anode in DMF in the presence of carbon dioxide. Reductive cleavage of the C-O bond followed by fixation of carbon dioxide efficiently took place at the benzylic position without any additive to give the corresponding phenylacetic acids in good yields in one step under neutral and mild conditions.

Ozonolysis of (alkenyldioxy)cyclododecyl hydroperoxides in trifluoroethanol gave a separable mixture of the corresponding a-hydroperoxy- and a-hydroxy-substituted spiro-tetraoxacycloalkanes with ring sizes in the range 7-12. Dehydration of the hydroperoxides or oxidation of the hydroxy-compounds afforded the corresponding peroxylactones. The solid-state structure of 1,2,6,7-tetraoxaspiro[7.11]nonadecan-3-one was determined by X-ray crystallographic analysis.

Methyl 2-,3-,4-carboxyphenylacetate and methyl 2-,3-,4-carboxyphenoxyacetate have been prepared through selective esterification of the aliphatic carboxylic acid function of the corresponding dicarboxylic acids using a mixture of phosphorus pentoxide (1 part), anhydrous copper sulphate (5 parts) and anhydrous sodium sulphate (5 parts).All the isomeric half-esters have been prepared through partial hydrolysis of the corresponding dimethylesters.
