The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.
