Abstract: The hydroformylation of allyl phenyl ether being studied; it was found that by the using of 0.2 — 0.4 % (w/w) cobalt as Co₂(CO)₈ and the reaction time 30 or 60 minutes best results are achieved, regarding both the selectivity of hydroformylation and the yield of C₁₀ aldehydes at 130 °C. The selectivity varies from 70 to 84 % and the amount of C₁₀ aldehydes from 64 to 83 %, depending upon the reaction time and concentration of catalyst. Aldehydes which were isolated from the oxo-product contain of the two possible isomers y-phenoxybutyraldehyde only. As by-products in the hydroformylation reaction mixture were proven to be present: phenol and minute amount of n-butyraldehyde, isobutyraldehyde, propylene and propane. The reaction mechanism revealing the formation of these products is given; first of all, simultaneous and consecutive reactions, catalysed by hydrotetracarbonyl cobalte are involved. Co₂(CO)₈ does not catalyse either decomposition or Claisen rearrangement of allyl phenyl ether.
