FIELD: organic synthesis. SUBSTANCE: method is carried out at elevated temperature and under pressure higher than atmospheric one with the help of carbon monoxide. The process takes place in the presence of iridium catalyst and iodide or bromide promoter, molar ratio of promoter and iridium 0.1/1-20/1. Thus pentenoic acids are prepared, namely, thus 3-pentenoic acid is prepared. Compound may be hydroxycarbonylated by carbon monoxide and water to adipic acid. EFFECT: improved efficiency of the method. 14 cl, 1 tbl
