ABSTRACT:
A process for reacting alpha-olefins having a single branch of the following general structure: ##STR1## where a,b and c are 7.ltoreq.a+b+c+4.ltoreq.40 and where a.noteq.b, a.noteq.c, a<b, with carbon monoxide and water or alkanols in the presence of a catalytic system consisting of a cobalt compound and a promoter selected from the group pyridine, a non-ortho-substituted alkylpyridine or a mixture thereof at a pressure of at least 50 bars and at a temperature of 175.degree. to 230.degree. C. into an isomer mixture of carboxylic acids or carboxylic acid alkylesters which is more than 50% acids or esters formed by functionalizing carbon atoms C.sup.2 or C.sup.3 of the general formula where the reaction is carried out with a promoter to cobalt ratio of 2:1 to 15:1 (atoms of nitrogen to atoms of cobalt) and at olefin conversions exceeding 50%.
