An alkyne-10,15-diol is synthesized by coupling a 3-alkynol containing methyl groups by using as a catalyst a complex comprised of a halide of a metal of Group VII of the Periodic Table coordinated with an organic phosphorus compound. The so-obtained diol can be formed into squalane [2,6,10,15,19,23-hexamethyl tetracosane] by hydrogenolysis, a combination of hydrogenation and hydrogenolysis or a combination of hydrogenation, dehydration and hydrogenation.
