Not water, but polyethyleneglycol serves as the solvent for the cobalt complex 1 (R CH 2 CH 2 (OCH 2 CH 2 ) n OH, n = 9), an efficient catalyst for the hydroformylation of 1‐hexene. Because complex 1 is not soluble in unpolar solvents, this highly chemoselective reaction can be conducted in the two‐phase system polyethyleneglycol/hexene.
