Abstract: The present invention concerns a process for the preparation of 2-(4'-nitrophenyl)-propionic acid of the formula (I): (I) More particularly, this invention relates to a process for the preparation of 2-(4'-nitrophenyl)-propionic acid (I) starting from para-nitroethylbenzene (PNEB) by carboxylation in the presence of alkaline phenates (Na and K). The 2-(4'-nitrophenyl)-propionic acid (I) thus obtained finds a useful application as an intermediate for the preparation of chemical products. For instance, acid (I) may be hydrogenated catalytically until obtaining the corresponding amino-derivative which is then condensed with ortho-cyanobenzyl-bromides in order to give isoindoline (as described in Belgian Pat. No. 774985).

Abstract: A process for preparing alpha-naphthol esters of aliphatic carboxylic acids by reaction of naphthalene with aliphatic carboxylic acids, consisting in the reaction of an aliphatic carboxylic acid in a medium consisting of an aliphatic carboxylic acid and in the presence of a system composed of a saline compound of cobalt II, of a ketone containing in its structure at least a methylene or methine group in alpha position in respect of the carbonyl group, and of oxygen, at a temperature ranging from 70 DEG to 110 DEG C.
