A process for the preparation of a polyunsaturated olefinic compound, i.e. undeca-1,3,5-triene, in its (3E,5Z) isomeric form, consisting of four consecutive steps starting from deca-1,4-diyne, is disclosed. Said process has the advantage of making it possible to obtain the desired isomer in its essentially pure form.
